Microsoft 365, two custom programs made specifically for the company at which I work and that only run on windows, and steam.
And before someone jumps in and is like “You can do all that on linux!”, I don’t want to use the web portal for Microsoft 365 because it’s terrible(I mean, 365 is terrible in general but the web portal is worse), I won’t be able to convince my boss to spend like an extra $10K to allow the programs to work on Linux, and yeah steam works on linux but it can be a lot of work to get certain games to run.
You make a fair point here. The pressure to just buy an iPhone so you can use iMessage is frustrating and downloading a third party app is really easy (and possibly a better option than iMessage) but you gotta remember most people don’t think like that. Honestly, I use signal for most of my messaging but still need to use text for many of my family members because I’m not about to walk my Dad through downloading, setting up, and using a separate app just to text me.
Also, yeah Apple could make iMessage available on Android but in the same vein Nintendo could make games for Playstation/xBox. They could, but why would they? People buy their hardware for the specific software that is offered. It’s frustrating but that’s part of their business model.
The real solution is to replace SMS/MMS with a better solution, which RCS is attempting to do, but it’s sub par compared to anything else still, in my opinion.
