I agree, but will that prevent the majority of the public from signing up? A bridge will collapse regardless of what the motorists think, but people being ignorant of Meta's misdeeds does mean that Meta's untrustworthiness won't—can't—factor into their decision regarding signups. Maybe Meta will make the news again with another scummy decision, and maybe that'll drive users away—but how many? I suspect it's a small fraction.

'Course, one might be able to make the argument about "the most important N% of users who create most of the content", who are also unusually savvy... I don't know empirical details here.

I should have said developerbrained. Most developers do not think like engineers. They nitpick specific implementation details because they personally prefer one of the thousands of other ways it could have been implemented. And they fail to understand why this one was chosen, as well as the bigger picture of the project, and then imply that whoever worked on it is an idiot.

Perhaps but the login thing seems totally tangential to this..
