I'm guessing it's an attempt to poison the well by pointing out that "I want to be able to choose which media I consume" sentiment is often employed by anti-vaxx nutjobs to protest social media censorship.

So some censorship is good?

Not OP. I thought it was really disturbing the first time I heard someone say they got "the jab" or "double jabbed".

That's just how vaccines are commonly referred to in the UK, long before covid.

That's not how vaccines had been referred in the US before 2021.

Why would that be disturbing?

Is that because you were previously unaware of an extremely common idiom?

I am aware of the term, having lived in a former British colony. It's hard to verbalize it. But it was just so sudden and became THE jab not just a jab, and people were talking about it everywhere. It felt very forced and like it came out of a marketing department.

It was not a regular term in US before Covid, and always sounded strange when British media used it.
