How do you defend yourself against somebody just mirroring the libraries?
I was just researching licenses for a similar business model (in a completely different field) and came to the conclusion, that it does not really work.
AGPL would somewhat work, but would still have the downside that commercial entities could use the software just for tooling and internal processes, which most software is used for anyway.
In my mind Open Source prevents commercial use of applications only if the software is very likely to be shipped to the client, for example Qt.
With libraries it might look different, because people just get used to them and want to use them everywhere.
Sorry for the late reply! Since the original upstream packages are all open source, there's pretty much no point in mirroring. The major value of such business is mainly commercial support, which includes maintaining compatibility and solving the problems that clients have with packages.

I would be very interested to hear your input!
