The stock market literally forces companies to be evil. Once you do an IPO, you're contractually obliged to be shitty in order to bring higher revenues.
Without anything extra, there are three ways of doing it:
Using Tailscale Funnel
Direct port forwarding in your router, and pointing to the IP using some DDNS provider (e.g. desec.io)
Through Cloudflare tunnel (not recommended due to privacy reasons)
In each case, you'll need a reverse proxy (e.g. Caddy) if you want secure https connections.
If you're willing to spend money, the better way would be to proxy through a VPS (using something like a Wireguard tunnel). In that way, you won't have to open ports on your home router. You can get a very cheap one since proxying doesn't need much CPU power. Just choose one with enough bandwidth. I personally proxy most of my stuff through a $12/yr RackNerd VPS.
I don't buy that logic. How is it cross-platform? (It technically is, but c'mon. All of these OSs are in the walled garden.) I agree about RCS requiring Android, but that doesn't really put it lower than iMessage, since that also requires you to buy a device. (iMessage does have more features, though.) Apple has promised to support RCS in iPhones, so this should soon change. Also, why would iMessage be rated higher than Signal using this logic? What's easier, buying a device or installing an app on your existing device? (If someone doesn't have any mobile device, I don't think they really care about messaging anyway. So I don't consider that as a proper prerequisite.)
LaTeX. As someone in academia, I absolutely love it. It has some issues like package incompatibility, but it's far far better than anything else I've used. It's basically ubiquitous in academia, and I wish it were the case everywhere else as well.
