NTA but there definitely are 2 very valid sides to this situation. On one hand, it is understandable that stuff gets delayed or cancelled because of all the moving parts and uncertainties going on behind the scenes like other members' schedules, management, commission assets, etc. On the other hand, Kanata has been pretty guilty of promising a lot and not always delivering on them like Undertale acapela, KING cover, more offcollabs in her new place, etc, that it's hard to blame heimins who become peeved or pessimistic about it.
It's good that Kanata has addressed it but only if she actually follows up with not over-promising stuff for a while.
Just a bit of personal speculation, I wonder if some of the sentiment is because Kanata's content has been somewhat stale for that past month or so, ever since the Minecraft festival it's been almost exclusively Rust, Powerpro and member only stuff, even most of her collabs have been Rust.
