As reported in a reddit post and confirmed in a github discussion, Simple Mobile Tools is being sold to ZippoApps which is known for shady business practices.
It is not yet clear whether they will make the app suite closed source (which would infringe the rights of all contributors since they contributed under the GPLv3 license).
In response to that situation, one of the main contributors forked the project under the name FossifyX and will continue to work on it.
he is selling his app suite to a comany known to ruin apps with trackers and ads, making the simple mobile tools suite no longer simple, but just another app in the ocean of crap. Also he likely violated liscences doing so
he could have at least sold to a better company, and considered the wishes of his fellow contributers as he have should according to his liscence
