'OS Qualtrics' that seems to just be using the 'open source' label as bait / marketing onramp.

From the second line of text describing their open source, self hosted version:

"(In the future we may develop additional features that aren't in the free Open-Source version)."

Not exactly a statement that gives great confidence in their commitment to Open Source.

It would be nice if these types of companies marketed themselves as "Source Available, cheaper than X" rather than 'open source'.

Open source feels misleading if you intend to fork it from the beginning.
