No because it's (probably) not a communist person/party doing it. Adventurism would be a party acting too far ahead of or without support from the masses. This is someone from the masses acting as an individual.

Unideological events like this, and the public reaction to them, can be analyzed by communist parties to gauge the potential of the masses.

If anything, this suggests communist parties in the West are tailing the masses. Which is to be expected given the extreme suppression and complex contradictions enabled by global imperialism.
