Lizzy felt trapped into making Splatoon content and didn't like that her videos were gaining popularity due to the content and not due to her as an individual. Her Vtuber-ing was her last-ditch attempt at escaping that hole she dug herself into.

Of course that didn't work and she knew that it probably wouldn't, so she abandoned the channel all together. She's glad that she did stuff on her channel, but she didn't like a non-insignificant portion of her audience (young children).

Some point after Lizzy stopped making videos the ClashB-Lizzy channel left her hands. From her period of inactivity onwards she wishes that she could delete all her videos off the face of the earth, pretend they never existed, and have everyone else pretend they never existed.

Also, she straight up said that the "out of her control" final tweet was a complete lie. Through some means, the party that now has the ClashB-Lizzy channel came to a compromise with Lizzy to private the videos rather than outright delete them.

She did appreciate most of her audience though, and even silently checked up on the channel once every few months for a while to see what the people who still watched her videos were doing.

I think that's everything. If I missed something, someone else will probably add it.
