First of all there are literally three upstream frontends (flang, ClangIR, and torch-mlir). Most people use PyTorch as a frontend (some people use Jax or Triton). Secondly, downstream users having their own dialects... is basically the whole point of MLIR. Core dialects like linalg, tensor, memref, arith are absolutely generically useful. In addition many (not all) MLIR-based production quality compilers are fully open source (IREE, Triton) even if wholly developed at a for-profit.
