Slack fosters vibrant (free) communities in open source and academia. I fear these are not long for this world.
Discord, on the other hand, seems to have built a "technical moat" of sorts for themselves by using Erlang/Elixir and other non-standard tech. Suppose SF or a company like them were to acquire Discord. If and when the staff were to leave once their vesting period or whatever is over, who would take over the codebase from them?
I hate to beat the dead horse but IRC sounds great for such free communities. If it’s just about connecting people without the need for historical data or discovery, IRC is great and won’t die when [tech company] folds
i think the constant comparison between the previous gen chat platform of IRC and slack/discord is just extremely tiresome.
