Ideologically I am a free speech maximalist, but I also personally despise being advertised to nonconsensually.
The issue with unadorned free speech maximalism (aside from people legitimately complaining about idiots spewing lies) is that it also dictates a 100% hands-off approach to even the most egregious spamming, as spam is legal.
As a fellow free speech maximalist, I think it's possible (and fair) to have a distinction between individual opinion and commercial promotion, especially on a commercial platform.
Free speech principles don't preclude some reasonable standards for curation of content. The key is to be consistent, regardless of perspective, and completely transparent. Where private, commercial platforms like FB, Reddit and Twitter have erred is in uneven enforcement of arbitrarily shifting rules which are hardly clear even when disclosed.
They were pretty much doomed to eventual failure once they started responding to subjective and rapidly changing woke sensibilities. Weirdly, I've read thoughtful posts by both Jack Dorsey and Zuckerberg which clearly show they understand they are being backed into a untenable 'no-win' corner yet still find it impossible to avoid.
