Yes? I don't think it's a very radical, unreasonable or difficult thing to provide: this is available as a first class feature on most blogging/forum software (RSS feeds) and wasn't even remotely controversial 10–12 years ago.
> They also seem to reinvent history such that there was some "implicit" agreement between Reddit and the users of Reddit.
There was an _explicit_ agreement: the site's terms of use have allowed free API access with reasonable quotas for 15 years, and are being changed now with very short notice. Of course the terms of service can change, but users are also free to leave, complain, or demand that they don't change. There are also strong cultural factors involved. For example: just like in the US it's customary for tap water to be free at restaurants, and people would be probably angry if you decided to charge for it, on the open web it's customary for some reasonable level of API access to be free.
> IMO, just because I wrote some shitposts on Reddit does not mean that I am entitled access to every single shitpost that has ever been written on Reddit.
There's no such asymmetry in scale: _everyone_ wrote the content, _everyone_ is entitled to access it. If you're referring to incredibly resource intensive, mass-access to download several terabytes for AI training I can see how that should cost a price. But they're blocking reasonable use-cases.
