I don't get these retarded individuals. They complained for years that commercial vendors do not support Linux-based operating systems with their softwares.
Now when these vendors extend support to "Linux", what they hear from these idiots is "Source or GTFO".
You should just write your own software where you can guarantee access to the source code and STFU.
That's because you are shallow. With new reports on backdoors everywhere the last thing I need is closed source app for communication.
With phone at least there is _some_ responsiility, with app there is none. If you chose to install it, practically any consequence is left as your problem.
So, for any closed source I would need certain level of trust towards its producer.
If I purchase Adobe Illustrator, for example, I could trust their name and reputation and suppose that they are after licence fees rather than my passwords etc.
But with practically no-name source for phone app ? No way !
And what is it that requires me to use such app ? With Adobe I can count on polished interface and plenty of high-quality, heavilly optimized filters that require mastery of the craft and many thousands of man-hours.
What is the reason for that security exposure here ? A couple of handy buttons ?
