What is worrisome about this development, and corollary actions like the hiring of a CEO with a $300,000/year salary, is that the essentially independent and community based platform will disappear. The ArXiv exists because mathematicians and physicists, and later computer scientists and engineers, posted there, freely, their work, with minimal attention to licensing and other commercial aspects. It has thrived because it required no peer review and made interesting things accessible quickly to whomever cared to read them.

A setup as a US-based "non-profit" is worrisome, if only because 300K is an obscene salary even in a for-profit setting. That the US-based posters can't see this is evidence of the basic problem which is that the US, both left and right, has been taken over by a neoliberal feudal antidemocratic nativist mindset that is anathema to the sort of free interchange of ideas that underlay the ArXiv's development in the hands of mathematicians and physicists now swept aside and ignored by machine learning grifters and technicians who program computers.

As a US based academic, I have to say when I saw the salary I immediately gawked. I think it's not americans but silicon valley-ites and tech bros on here who have lived with inflated salary/net worth that think it's just a middle of the road salary. As I regularly interact with friends in engineering who make like $200k + benefits ($), and I wonder why I don't jump ship to that weird land.
