That's great (genuinely), unfortunately having to work outside of the mainstream brings its own hurdles -this isn't on the same level but consider twitter vs mastodon or reddit vs lemmy: the corporate solution is shiny and easy and requires very little to no effort from the end user to use, while the other requires a little more understanding and effort and comfort with technology, and might not appeal, or even be known, to many. Sure, people can look it up and learn it, but that looking and learning are hurdles, and when it comes to accessibility devices, those hurdles tend to be more significantly in the way.

To be clear, I am not trying to shit on the open source stuff, I do genuinely think it's great, but like so many of the solutions we currently have to work with, it's a band-aid on a cancer. We need to remove the cancer.
