The MI25 wasn't targeted at the general public, but it wasn't hard to buy one. And the customer products using that same die, Vega 56 and 64, were sold quite a bit.
What affected the community severely might be the combination of both GFX8 and gfx900 going away, leaving only MI50 (Vega20, also used in Radeon VII consumer variant) and no support (only unofficial enablement) for the later customer products. Because those went GFX10/Navi.
