I am sorry we had this impression. Sure, we use ANTLR a lot, for commercial and open-source projects, and we had to work with parsers written in (flex), yacc, and bison, so we shared our experiences as people who work all day long with parsers. We offer a lot of free resources on ANTLR and we have not specific interest in advertising ANTLR. For us it is a tool we use and love, just that

Almost anything fares better than flex/bison, this is shooting the proverbial fish in a barrel.

It comes across very strangely that your brother writes as if y'all are unaware of the existence of parser generators other than ANTLR. This makes me sad. In a fair comparison, ANTLR really is not a great tool; its capabilities are eclipsed by its marketing.

We have several articles comparing tens of other tools. That said of all the tools we worked with, ANTLR was the one we were most efficient with. It is true, there is a learning curve, but in our experience learning it was a great investment. I can understand other could have different preferences
