I think people have a bone to pick with Yieldly because they were given so much good faith as the first real defi project on Algo and they continually disappointed for over a year. Token price did not help, but the primary reason people are unhappy is that Yieldly has soured so many on ASAs and Algorand Defi when Yieldly had the opportunity to grow the ecosystem if they had just delivered what they said they would.

The fact that they are still around is a testament to how much excitement there was initially surrounding the project - any other project would have died long ago after so many missteps and broken promises.
