People are definitely waking up, yes. That's part of the plan, too. The powers that be have internet access, and in many cases are just as smart (or smarter) than the average person, so they're aware that people are waking up. For some reason, we forget that, and act like we might be pulling a fast one on them. We aren't! They're on to us "awake people", and have been since before we were awake.

"telling people to get their flu shot to keep them safe from ‘Covid19’, the above example from a rural Arizona highway"

I don't see it claiming the flu shot keeps people safe from Covid, but maybe it said something else before or after you took the shot? It seems to be the standard "get your flu shot" message that is always being broadcast in such locations. You're right that the flu shot is pointless, especially right now, with all the masks and lockdowns, there's almost no flu out there. What little flu there is, gets relabeled as Covid.

Tom MacDonald has lyrical skill, but he's half woke, and his lyrical content is a limited hangout. For example, mainstream cancer treatment is a trillion dollar a year industry, and big pharma is public enemy number one, but Tom neglected to mention there are alternative cancer treatments. He focused on the strength of the cancer patient, but didn't offer a solution, even though one is readily available. He's about Tom first, and the truth second or third. That's okay, I'm just saying, there are better hiphop artists out there, who don't pull punches and protect the state with what they aren't saying. That said, Tom wouldn't have got the audience he has, if he had gone head to head with the state and big pharma. He'd have been taken down by now if he was a real threat to the system.
