Americans not understanding other countries exist, an exhibit:

why don’t you tell us how you really feel

data can’t leave the EU without explicit consent

This is already more or less the norm for many services, because of the GDPR and the ePrivacy directive, especially if you’re handling special personal data categories, and/or the service is for a government entity. There’s some caveats to this, but on a general level that’s already how things are.

But as was pointed out, the problem isn’t getting folks to host things in the EU since it’s not like only European companies have data centers in the EU, but to use European cloud providers. Vendor lock-in is a real issue, however; no European provider can give you what AWS or GCP can, and migrating to something else might require a lot of work depending on which services you’ve been using.

So mind telling us mere mortals what your point is, then?

Just asking why anyone would want to publicly host the repo for a closed source project isn’t a point – it’s just you not understanding the reasons for doing that, and just because you personally don’t understand something doesn’t mean there’s no valid reason to do it.
