Cosmic Inflation confirmed? Really?

After all the fuss about cosmic inflation being confirmed earlier this year by the alleged detection of gravitational waves . . .

As usual, the retraction of a sensationalized claim gets only a fraction of notice achieved by the original hype! (Did you personally catch the retraction??)
In an article in Nature, Princeton University’s Paul Steinhardt gripes, “. . . the inflationary paradigm is so flexible that it is immune to experimental and observational tests. . . . the paradigm of inflation is unfalsifiable. . . . it is clear that the inflationary paradigm is fundamentally untestable, and hence scientifically meaningless.”
