I lived in a country doing that, and couldn't understand the people making social media profiles with their (actually traceable to a real life identity) phone numbers public. Don't you love receiving spam calls?
Remember that banking and finance is full of regulations, and have moving speed of snail. Opposite of IT. When asked for something like this (open source or cross compatibility or anything nerdy) the first question is "who will be liable for losses and damages when something breaks?".
Liability is probably the biggest factor. When something isn't working properly, they want to be able to point fingers at someone and blame them. The vendor then blames someone else. Open source tends to be the polar opposite, which means huge red flags - hippie stuff, no payment, no liability, no pointy-blaming game.
Or so I've heard from people working in that sector. For places as conservative as them to deploy FOSS solutions, you'll need the government branches cooperating with clearly worded laws and regulations, dragging them kicking and screaming into adoption.
And that's assuming no one will lobby against in the process.
There shouldn't be, but that doesn't mean it cannot be enhanced. Hopefully a popular feature from an extension can become integrated into official web clients.
There are videos I still visit and were uploaded more than 10 years ago. It would be a shame losing them all, pieces of internet history instantly gone.
To be fair, you can be a developer maintaining a website or an app for a company that operates on stuff you have no idea about. Working for a hospital doesn't mean you can perform surgery.
Sorry for the late answer. I ended up choosing Midagu for the time being. Unlimited inbox sounded attractive enough as using alias in my use case wasn't cutting it.
Help me understand something, DNS records are the info (A, AAAA, TXT, etc) that's modified to configure services like websites and mail servers to a specific domain, right?
I hate apps and services doing that.
