ITT: We post opinions that will trigger /vp/.
I'll start; Lando-T is fine and shouldn't be banned. It's usage is high due to it's versatility. It's a Pokemon that has many different sets that can fill a variety of roles. It's functionally like 5 Pokemon in one, resulting in a high usage as it fits on basically any team. It's not meta defining, nor is it OP. It's beaten by a lot of OU Pokemon and can be shut down if you know what set it's running, which is easy if you know what you're looking for. /vp/ just hates it because it's ugly and popular in OU.
