You're correct that Verizon has always been the only provider that had access to the Pixel line, however
he did not say "Welcome to the party Verizon, you're finally not assed out".
What he said was : "Now this phone is available for all of the carriers, so shout out to everybody with Sprint and Verizon. You finally not assed out, welcome to the party".
Yes I paraphrased slightly but my point is still the same. His statement clearly implies that if you are with Verizon, you were "assed out" at one point. Which is not true. Not a big deal. He's just being lazy with his facts. And his video editing, which is why his videos take several weeks to watch.
