Perhaps, the issue is that the pace at which they release open models compared to their closed ones, shows that they are more committed on the closed ones and are not interested in advancing the state of the art of open models.
I can't say what they should or should not be doing.
Generally, it is conspicuous how American companies are absent when it comes to state of the art open models. Meta tried for some time but it seems they've given up.
Should they be interested in advancing state of the art open models?
