OK, then this has been the de-facto standard amongst many industries for a long time. Plenty of reviewers say stuff like "it really is weird! I made one video about how I didn't like a product. After that I was never invited to attend a launch for a product, get early access, etc. I guess those two could not be correlated at all!"

Based on the text you have shared it'd be perfectly fine if you were paid to write a "neutral" review.
