"Salieri didn't like Beethoven's late works."

I remember that the concert introducing the fifth and sixth symphonies was widely criticized. This was mid-life, not late.

Edit: I don't find evidence in the wiki of hostile reception, excepting this:

"The concert provoked the ire of fellow composer Antonio Salieri, who had been Beethoven's teacher. Also on 22 December, Salieri organized his annual concert to benefit widows and orphans, and he threatened to ban any Tonkünstler-Societät musicians who had played in Beethoven's concert instead of his own. However, soon after the relationship between the two composers improved."
