There's an unspoken rule in hololive, enacted by the holofandom, which is that you must either demarcate your apathy for streaming explicitly, with some sort of verbal declaration (excuse) or consistent pattern (Ayame), or not be apathetic towards streaming at all.
This point is obviously salient when you look at the holo streamers with the most loyal fanbases: Amelia, Ina, Kiara, etc. They have consistent as fuck stream times and streaming weeks, and will let you know if there are any changes to their regular streaming pattern.
Mumei encapsulates this perfectly. She clearly has an excuse (valid or not), mentions it explicitly, but still shows effort and interest in streaming. She gives you a guerilla Karaoke after a long college day, as she is quite literally falling asleep from exhaustion. That's commitment.
Baelz is another recent example - she streams regularly and often, has built up a loyal fanbase (used to average 1-2k viewers 2 weeks after debut, now averages 5-6k minimum), and had a valid excuse (internet dying out) that she mentioned EXPLICITLY to explain her sudden change in streaming hours. Brrats are happy with that.
Fauna is the same: tooth surgery. Irys as well. This is why their viewership is so fixed and there are no massive fluctuations in their CCV (Fauna is, comparatively, Ina-tier when it comes to viewer retention. That's loyalty).
KRONII, on the other hand, has failed to deliver on all of these aspects. These sound pillars of good streaming.
(1) You come to expect a variable streaming schedule
This is by far Kronii's biggest mistake. A variable streaming schedule is a surefire way to destroy any viewership loyalty, as your fanbase finds themselves catching fewer and fewer of your streams until they just decide to stick to clips or to drop you entirely.
(2) This variability is marked by a reduction over time
This is a massive issue. No EN besides Amelia has actually reduced their streaming over time, and Ame did it 1 year later after months of extremely committed streaming hours.
Kronii? 1-2 weeks of frequent streams and stream time, then suddenly, after breaking EN SC and membership records, she just stops. Stream frequency goes down a fucking cliff. That's a big mistake paired with (1).
(3) No explicit excuse
With the exception of this week (a little too late, viewers are skeptical of how genuine your excuse is), Kronii has not given an excuse for her horrid stream times.
She has not told us about a second job, or some familial commitments, or maybe that she flat out just doesn't want to stream as often. She keeps everything under wraps, which is not only damaging to her fanbase loyalty because viewers come to distrust you and your effort into hololive, but moreso it represents your rigid adherence to kayfabe, to not open up to your loyal fans but remain a fixed distance from them.
Case in point: the bond level thing was dropped 2 weeks ago, after being mentioned almost every stream.
Case in point 2: Mori, early on, suffered from highly variable stream times, but kept her fans loyal because of her very valid excuse of holding multiple occupations.
(4) The jury is out: appears for more hours on other people's streams (in VC) than on her own.
This is by far the biggest knock against Kronii because it completely omits many valid excuses one can come up to defend a lack of stream time and stream frequency.
It is the fact that 3 weeks ago, during the big EN MC portal build, Kronii streamed for a relative 7h but appeared on other stream's (and VC) for nearly 10h.
Then, you have chumbats stalking holoEN MC server activity, and just what you see from JP/EN MC streams recently, and you can see that hasn't changed. Kronii is clearly comfortable being on camera (in voice) in her free time, and has a LOT of free time. Why isn't she spending that free time with her viewers?
Finally,
(5) apathy.
Kronii's general nonchalant and apathetic attitude, intonation, and approach towards streaming has soured the previous four points tremendously. It isn't her fault, per se, as long as the apathetic attitude is just a part of her tonic everyday personality. But it does leave a bad impression. Coupled with everything else you've done? Not a good look.
There are many other things to pick at.
Her failure to live up to her membership promises, for example. Her lack of social media interaction. But those are quite nitpicky, and really applicable to any holo if framed the right way.
Kronii is bleeding fans, support, and general good will from the hololive fanbase. Her own split has turned against her, and I am very sad to see this as she is one of my favorite ENs. Kronii, for your own sake, either man up to your lack of interest in streaming or start streaming more often. I will be canceling my membership by the end of this month if I do not see improvements.
