DON’T say the things that developers who ignore consent typically say
That’s likely to increase the pushback. If that’s your goal, great, go for it! If not, though, it’s best to avoid stuff like this.
“Posting publicly gives implied consent to use the data”
I don’t inherently agree with the article’s ask, but you’ve literally only proven its point by stating, verbatim, one of their “please stop making us retread these tired arguments over and over” points.
OP links to a Mastodon thread from a user who breaks down the technical limitations of ActivityPub and proposes how the situation can be improved. Maybe read that.
Also, if you think that these are reasonable suggestions, then perhaps ignoring them directly isn’t the best way to engage with this article?
