Fossify Gallery on the official F-Droid repo
The removal isn’t directly related to the buyout/fork. Simple Gallery was taken off of F-Droid due to a dependency on the nonfree Google VR being discovered by IzzySoft¹ ². Fossify’s fork has removed the dependent features to be compliant³.
The SMT apps after the buyout, are not necessarily bad either, it’s up to the new owners whether they want to keep a FOSS version as advertisement, or not.
Aren’t there outside contributors? How can they relicense it without their permission?
They can’t relicense it without permission, what they’ve done right now is fully allowed under the GPL: they’ve started charging a fee for the binary.
The GPL allows anyone to:
So they’ve switched from case 1, to case 3 (and maybe 4).
At any moment they can keep any part of the apps, or any of the apps, back in case 1, while asking for a fee to access the other versions (like the “Pro” ones). If they did so, then anyone who paid for a version, could ask for the source and decide to publish it for free as in case 1… or not, it’s the buyer’s choice now.
The “kind of dick move” effect, is that F-Droid was carrying a “Simple Gallery” version which now shows a popup requiring people to pay.
Going forward, F-Droid is carrying the Fossify Gallery, which is the same source with changed branding and no popup. SMT could still play nice and offer a “non-Pro” version of the apps that could get carried by F-Droid, which could lead someone to pay for the “Pro” version. Equally, random people could pay for the “Pro” version and make the source available to Fossify for free so they can port the changes, then have the resulting app carried by F-Droid.
So it’s up to the new SMT owners whether they want to play ball, play hard to get, or get forked away.
Removed by mod
Yeah I know that’s allowed under the GPL, but you mentioned them “choosing to keep a FOSS version”, which if they didn’t do that would mean relicensing. It’s still FOSS here.
I meant it in the sense they could discontinue the FOSS version and roll their own privative one in its place. They’re “simple” apps after all, wouldn’t be too hard to make a simple clone. What they’ve really bought is a trademark/placeholder (along or not with a company, I haven’t looked much into the details).
they don’t care and as long as no court ruled, they do what they want, which will probably work out for them
