Beeper does in fact support those (and more), also through reverse engineering efforts.

They're trying to innovate in the space by building a single interface to multiple services, but anticompetitive action from Apple (and others, I assume) is preventing that from happening. It seems to me like an obvious thing to regulate. The benefit to consumers is obvious too.
Stories/Reels/Posts Sharing: Not supported.
End-to-end encrypted chats: Not supported
WhatsApp:Will view only once messages feature work the same way like it does on WhatsApp?
No. Currently we don’t track when users open media and hence cannot support it in a similar fashion. Such messages will remain on Beeper as any other encrypted message.
In theory this could all be added later on, reverse-engineered later on etc. but in reality this is much more likely to become a niche or fail outright. Threema and the likes have survived for so long because they don't try to break into third party systems. It's not a new concept, and cat-and-mouse with third party servers has always been an unsuccessful avenue.Hence the political efforts. If Apple can be forced to enable interop, everyone else can be too.
The only reasoning behind the whole iMessage thing seems to stem from a specific age band of Americans that value others based on the background color of their messages. This is a human problem, not a technology problem.
Why should service providers be forced to police CSAM and hate speech? Because it makes sense to weigh individual freedoms against the cost to society. (and keep in mind that Apple is a publicly traded company)
The cost of walled gardens are that they harm consumers. Consumers need to spend more money to overcome artificial barriers designed only to increase the amount of money they spend without offering any value. Interoperability for commodity tech like this is an obvious win for the economy.

If that's really what you think this is about, then you haven't been paying attention to any of the discussions on the topic. Or you're doing the thing internet people do where you're being disingenuous just to win an argument.
