I was also a little confused about this, because I vaguely remember slack locking down its API, and people complaining of the resulting inability for switching to a different, and possibly more efficiently implemented, UI
can't comment on the original comment you made here https://news.ycombinator.com/item?id=20500181 because it's now flagged, so commenting here to state: There is a deafening irony in deplatforming a post arguing against deplatforming as a valid tactic. I hope it is not lost on the HN mods. ;)
Bringing ideological battle into completely unrelated threads is definitely not ok. Please don't do this again. We want less ideological battle on HN, not more.
It's not an "ideological battle" if it's empirical (based on evidence and rational discourse).
The only "ideological battles" are religious in nature. I'm fine with keeping religion off HN, but you can't just call a contentious topic "ideological", especially if there is evidence and/or rational debate to be had. The fact that an insufficient number of people opt-in to discussing some topic in that way does not make it "ideological". Would you also consider conversation about climate change "ideological" and thus unworthy of HN?
In any event, the original post (interestingly) got unflagged, so this was superfluous anyway.
