@cmhobbs I have a web tech blog's RSS in my feed reader. There's no week without 2-5 articles on Slack or referencing it. Must be some sort of fancy web hipster stuff.
@tuttle Last weekend I was ready to stay home instead of going to a "fix/remake" workshop (me representing !umehack) because they hadn't setup _any_ communication outside of walled gardens (apart from collecting emails).
I had told them they should get just an ordinary website. It didn't happen until I explained that only supporting walled gardens directly oppose a hacker ideology, diminishing my motivation to help. Also their mails had "Sent from my iPhone" advertisement, despite Apple's infamous environmental disservices (not ideal for the workshop!). I had to ask them several times to remove it before they did so.
I think it's important to show those who want help from the !foss community that what we do is in fact important and that centralisation of the internet is bad for _all of us_.
Our common struggle is in fact so important that we _should_ say no to "bad deals". If we don't say no to #Slack, #GitHub, #Facebook etc. it's effectively the same as saying _yes_ to them.
