While it might suck for some people, the 10k message limit was always there, so if you wanted to keep history - why the hell would you be on slack?
And the people here shouting matrix and "don't go to discord" have never tried to push more non-technical people onto it. It starts with differently named apps on desktop and mobile (sure there are a few multi-platform clients). But then the naming? Back in the old days, IRC for a lot of people was not IRC, but mIRC. Why? Because the icon they had to click had that name. Thank goodness it at least resembled the name of the actual thing they were connecting to, where they could go "IRC? you mean mIRC?".
If I now tell someone to go on matrix - they don't have a matrix app on their phone, Mac or pc, and I have no idea which-one it'll be. Branding and name recognition is important here.
