I used to use a multiprotocol client, Pidgin, to chat with people on a couple of different platforms. But of course now a lot of chat is on things like Facebook and Google Chat which are supported only by plugins. But even that is still not enough because I will have to have an account on each of the platforms.
Chat really needs to be like email or SMS; you ought not to need an account with the provider of the person you are sending messages to.
But seriously, there's zero incentive for the folks building these clients to make them interoperable. In fact there may even be disincentive, since the more folks they have on their platform, the more valuable the platform is.
Bringing it back to the topic on hand, this is very much an area I wouldn't want to see a heavy handed EU legislate something that just further cements the incumbants and makes everything worse forever... just like mandatory micro-USB would have been. I can totally see the EU legislating something like a mandatory Meta communication protocol with compulsory attestation from Meta servers.
Which is good, because the Lightning connector has DRM in the fucking cable, and gave Apple outsized and undeserved control over iPhone accessories.
Think about how long it took to get email spam under control (and even so it remains a problem). Think about the ongoing problems with spam phone calls. Now pretend you are someone with no technical background, someone who only sees the UI and does not really understand what happens behind it -- you are not seeing spam on closed systems, you are seeing spam on open systems, what are you going to choose? Also keep in mind that there are worse forms of abuse than spam.
Maybe aside from the increased attack surface and trust issues...
If you want people to adopt your thing, it's got to make their life easier, right now, full stop.
But somewhat counterintuitively, you can do that by making their life a little harder first.
For example: leave Facebook/WhatsApp, refuse to communicate over SMS. Have good reasons for each, so you don't come off as unnecessarily difficult. Explain that Signal is far more secure and private than either and just as easy to use. Then using Signal is making it easier to communicate with you. It worked for me.
I left the whole Facebook ecosystem about 10 years ago, but never deleted my account. I left it up as a tombstone that makes it very clear I'm not there and tells people how to contact me.
There are certainly parts of my life that would be more optimized if that weren't a constraint.
You misunderstand. I have had to use various apps to communicate with people I dont need to talk to again, e.g. hotel and airbnb hosts in different countries which use these services. Like the time I had to install whatsapp in Spain to get into a boutique hotel. Sometimes you are meeting someone, e.g. a potential client who only uses signal so I install signal for our meeting and promptly uninstall it after we are done communicating. I have also had to install signal when coordinating with others for a hackathon and dumped it afterwards as we all had email addresses.
I think you underestimate how little tolerance the average person has for this kind of friction. These huge platforms win because everyone is on them and it all just works.
> After that you forget it exists until someone messages you.
Until you get a random notification asking you to take steps to keep your account active or whatever. You may not care about this, but many people get stressed out about this kind of thing.
