They did build a better alternative - Slack, then Teams came along and tried to rebuild Slack and then Skype and then Bluejeans came along... and then Zoom... and then Discord and the comms environment keeps evolving and the rent keeps going up.

Whatever you build on will be ripped out from under you and you'll be forced to evolve, just as we all have had to since the beginning of software engineering.
One thing is true as has been since the beginning - the next generation always knows better than the previous until life bites them in the ass and they learn their lessons the hard way too. As sure as the sun will set tonight and rise again tomorrow. There's little point in complaining about it. What will be, will be.
