Before someone says "but China broke free". China is an exceptional nation with a huge army of geniuses. No other nation can do what China does. If it was any other country, their smart phone company would have died.
Deepseek gives away their AI tech.
Agibot gives away their robot tech.
Others don't even need to steal our ip. Chinese companies are giving it away for free.
This is ultra stupid.
You have it backwards. Open sourcing is one of the most powerful way to monopolize in the software industry. Look at Linux and android, both of those OS are borne out of open source projects and now the majority of phones and servers run on Linux. By open sourcing the code you're basically opening up the software to crowd funded research rather than doing it on your own.
Somewhere along the line they must have realised that what they were doing is not so ground breaking that nobody else can replicate it.
if it is better than other implementations, suddenly all their competitors will have to face the difficult choice of dumping what they have already done to copy your software OR spend more RnD money just to reach the same level as a open source project. In fact to keep pace with a community project which will include elites from top universities all over the world, those competitors will need to devout vast resources.
Meanwhile, you retain full infrastructure and know-how on your project, you will retain competititive advantage over your opponents as it's a community project, far more devs are happy to use it due to familiarity. This is why so many devtools and engineering software is free for university students, familiarity now means market later.
There are also hardware versions of this. Tesla is so confident regarding their competitive advantage compared against incumbent legacy automaker they release all the patents for their EV tech. It did not help the competition.
Setting the standard is an incredibly powerful tool to carve out space in a new field.
