I agree with you. The move towards platforms like Slack and Discord where you need to be logged in to see anything at all is a terrible one, and it basically kills discoverability stone dead. Also gonna make for an interesting future for Google if it becomes the norm, since it's also unusable in their search engine.

Alas, it definitely seems to be the direction these services are going in, and (at least in my opinion), seems to be on the verge of outright replacing Reddit for communities about games and media related topics.
