Can't really make out the tone of the question, but I'll try to answer anyway. If by selling we refer strictly to "exchanged data for money", then no, based on the Senate report there is not direct evidence of that. Based on the same report though, the tax sites had business agreements with Facebook to include the pixel and, again, even if they didn't receive any money per-se for that inclusion, they certainly benefited from it (via Lookalike Audience and generally, improved ad targeting). So, does Facebook (and Google etc) sell your data? One can argue that technically they don't. Are they making a profit from having (and using) that data? I'll let you answer this question.
