I think some of people knew about it, but they was accussed of conspiracy theories, but (aluminum foil) hats off, here is why Radeon GPU's have so low market share:

I know, this is in Polish, that my native language, but as you can see, if you have Integrated GPU on your CPU, Steam will read your (for example) 9070XT as AMD Radeon (TM) Graphics. I already reported this on steam, where i could (2 threads, including steam beta channel), but AMD should be also aware, as if there are (Nvidia users says there are) devs that rely on this survey, this damage the market.
If we take in account all data, marked with red from first screenshots, and summ this up, all steam hardware survey looks different:

And whats strange - data from this survey from linux only shows something different:

In the end, AMD, according to Steam hardware survey got 17%, but most of radeons are not showing on the list, because of that.
Spread the word, i hope Valve will fix this. For now, only disabling iGPU will "fix this" (no VRAM?)
