Playing devil's advocate, but why is that a big problem? large tech companies aren't altruistic and leadership isn't stupid. If shipping fast gives them a better competitive advantage than writing OSS, why should they invest in OSS?
It really depends on the perspective you're looking at the situation from. If you're concerned with better competitive advantages and the final bottom line for company X or Y, in this current market, in the short term, sure, that sounds amazing, sign me up on that moon rocket!
If your concern is a bit more hard to quantify, for example maximizing human potential, allowing individuals access to high quality technological infrastructure so that we may develop as a species and reach new heights, then you might feel like this approach is a bit short sighted.
unless the company doing this can reap exclusively those new heights, no one will be altruistic enough to make such an investment to the betterment of mankind!
This role is left up to the publicly funded institutions such as gov'ts.
Amorphous long term ideals are great but if you go broke tomorrow you aren’t doing much OSS development next month.
I'm not looking to be a shill in this thread but we might be what you're looking for, and even if it isn't, I'd love to keep in touch as my own life goals involve leveling humanity up in some capacity.
