This practically means nothing tbh. Social networks when they gain economies of scale due to the network effect will effectively shed all the pretense of open source and open platform etc.
We've seen it with Facebook, Google, etc, during the 2010's with closing of chat standards and destruction of XMPP. Reddit 3rd Party API access is another example of this. We'll see it again.
CHIPS was always going to be a giveaway for nothing. It reminds me of that FoxConn CEO's quote about the fact that the US could pay them to fab in America but nothing would actually come of it. Then they just dropped that $10B Wisconsin project as soon as possible.
That was under Trump. Biden literally saw this and doubled down thinking that TSMC would roll over.
I think one thing you guys should keep in the back pocket, is that Mozilla jobs are the outlier. The average Open Source Developer salary is very close to the US Federal poverty line. They're paid mostly in comped passes to conventions. Most of the "averages" you see are compiled from data from companies like Mozilla. OSS devs are typically make around $30k in pure cash, even for ones working on large projects. The only OSS devs that make between the $95k and $150k (25th and 75th percentiles) you'll see online are ones that work for Mozilla, or Intel, or whoever.
What makes this possible is MIT licensing models that corpos shilled in the 2000's and 2010's that directly benefit corperate engineering costs, but don't contribute back nearly the value they extract. If the majority was GPL + copyright assignment, there would be income streams for leveraging OSS projects in closed source applications via licensing deals.
But the genie is out of the bottle on most of these things. See how Amazon is effectively forking an destroying existing OSS models via AWS provisioning of things like redis and elasticache.
They're the same answer.
You need money to market applications to users. Bluesky is sold the same way that Twitter is, your favorite moron celebrity might hit like or retweet on your stuff.
