I didn’t mean that they’d limit it to their own components. It wouldn’t be usable in such a form. Just that by seeing it as something complementary/synergistic to their real product, rather than seeing it as a profit center in its own right, they might subsidize it in part or in full.
Consider how ARM (IIRC) subsidizes PlatformIO, even though PlatformIO supports countless non-ARM MCUs, too. Or how Analog Devices subsidizes LTspice, but in no way restricts it to only working with their components. (Sure, TI chooses to release their spice models only for PSpice and/or TINA, but absolutely nothing is stopping them from releasing LTspice models if they wanted to.)
Or how Microchip and ARM both have free standard versions of their toolchains (MPLAB X and Keil, respectively), but sell upgraded ones for those who need every iota of performance, or things like safety certification.
