That’s a hugely disingenuous counterargument. It doesn’t so much move the goalposts as sets them on fire over a pile of explosives and puts them somewhere in low orbit.

To that question the genuine answer is “what the OP is proposing is not a boycott”, then.

None of these “don’t support them with your money” online liberal fantasies are boycotts by the standards you’re setting. If anything, going back to those examples to get a grasp on what an actual boycott looks like in the context of larger action only exposes to what degree this nonsense isn’t that.
