Darktable has a great piece of code for doing perspective correction that could be very useful to do before cropping.

@alan_g principles still do apply. You just have to compare track records with FOSS from Github and from Microsoft.

FOSS people will not embrace Microsoft and are leaving Github by the thousands.

Shall UBports stick aroung and wait to be thrown in the same bucket as Microsoft by the FOSS comunity?

Many Linux folks still say Ubuntu is a spyware years after the issue has been fixed. The name stuck. So don't expect now that everybody will be "rational" and I guarantee you UBports and Ubuntu Touch might be dismissed by some people for not taking a firm stance now.
And UBporrs will move to some other service one way or anorher because there will always be somebody new to start this discussion again, again and again.

@flohack day 0 damage control.

Move to GitLab, UBports should make at least a firm commitment to move to GitLab in the next two to three months.
Community will forgive if this delays other plans for UBports a bit. What they won't do is contribute to a project that doesn't make it clear they do not support Microsoft's agenda and wont stand for their embrace extend extinguish.
Let us not forget that Unity failed to GNOME mostly because of Ubuntu CLA and similar stuff that didn't align with the foss philosophy in the minds of many Linux devs and users.

This is more than just a PR move, this is about how we do this things in the future too. I say let us not do compromises in face of events such as this one. Make a firm statement that UBports does not do compromises and that UBports will move to other service even if Microsoft doesn't have an agenda, do not wait to see the negative impact, make it clear that UBports will be paranoid so that you don't need to be, so that you could have a peace of mind.

A piece of software that is free and doesn't have any proprietary attachments because UBports is not Microsoft and wont stand for their agenda even if they buy GitHub and try to shove it down our throats by their corporate force...

This move will most surely strengthen the bond and the trust between the project and it's community.

@alan_g has some good points and I would agree with him if we were together in a company but sometimes, like in this case, the most economic and the most efficient thing isn't the right thing to do.
