Why are all of the Chess.com bots unlocked if I don't have a membership?

Every Chess.com bot is currently unlocked for me. I have no idea why. Is this a new update? 

If it is a new update, that's great!

If it's not...

You might be that one kid that reminds the teacher they forgot to assign homework...

Yo it happened to me today

WTF

Me too. But how???

It was a change in how bots are handled. They're all available to basic members now

Why are they locked again?

bro ANYTHING but making puzzles free for everyone ;/

Oops I haven't done geography homework for 2 months

Surely my teacher won't notice if I don't do the homework again right?

Possible reactions:

1. Making some feature paid → bad
2. Making some feature free → bad

Understood

damn it...I wanted to play the Andrea Botez bot but I didn't realize they WERE unlocked 26 days ago but now they're locked again.

please explain why many bots are locked again.
