After decades of corporate propaganda, the mainstream view is that "goverment can't do anything".
This has led to people expecting the rich to donate for this sort of outcome, instead of demanding better organization from the government that's eating away almost half their income.
Adobe could easily make a one-time donation of $millions to set up an endowment which would keep them running for the foreseeable future. The government could as well, I just see it as less likely. The government seems much more likely to maintain an active control over something like this, opening up the possibility of political interference in the future.
