Is there a reason that these ML models are being hoarded as "secret sauce" when, for these companies, all the rivals they're concerned about also have all the resources required to build one that's nearly as good? It feels strange that we've got six different tech giants that have all independently spent tons of capital building up the training data required to sell people smart speakers/mobile speech control/etc. with these ML models, without any of them entering into cross-licensing agreements.

It seems like it'd make a lot more sense for Apple, Google, Amazon, Facebook, etc. to all pool their training data in an "industry working group" to build and license out one "best" model, the way that IWGs are formed to build and license out e.g. AV codecs.

The press would skewer them alive and politicians will have a field day about tech companies violating privacy and sharing data.

It's bad enough that one BigCorp has my data. I'd rather not have them also give it out to every other BigCorp

ML is an extremely competitive field right now and everyone's trying to get an advantage over everyone else. Not too ripe for cooperation right now.

It's the same reason car makers don't all use the same platform. Everyone is hoping to get a slight edge over the others to preform better in the market.
