I think it's more a consequence of pushing for the biggest valuation/IPO. Rumoured profits on inference are north of 70%.

Taking SpaceX as an example, they have increased prices across all their consumer products over the past six months. But they definitely aren't short on money with Alphabet and Anthropic combined paying them over $2 billion per month.

Microsoft/GitHub lost out here as they were just repacking other people's products.

Inference can only happen after having invested in training and datacenter construction. Arguing about "inference profitability" sounds a lot to me like ignoring large cost centers of these comanies.
