Chrome controls ~73% of global desktop browser market share. Add Chromium-based browsers (Edge, Brave, Opera, Vivaldi) and the figure exceeds 80%. Mozilla's Gecko (Firefox) is the only viable independent rendering engine.

Developers test and build for Chrome only. Agriculture teaches us how dangerous monocultures are.

When one company controls the dominant rendering engine, they effectively control which web standards are implemented, which APIs exist, and what the web can do. Alternative protocols sidestep this entirely — they don't use browsers at all.
