I disagree. The guardian article reports that according to some US senators, facebook permits ads that contain 'demonstrably false claims'. However, most of the article is about misinformation that is actually more subtle than having false claims.
It seems you mistake misinformation for false claims. They are not the same. Misinformation is a truth claim that has the intention to deceive in order to further an agenda. It's doesn't even have to be false!
For example, Shell used to push really hard that it 'planted 5 million trees' and invests in renewables in the Netherlands. The intention was clearly prop up a reputation as a green company. But actually, that investment is not even a blip on the radar compared to their continued investments in fossil fuels, including exploring new sources in the arctic, which is completely incompatible with the Paris agreement. This is pure greenwashing and rightly called misinformation, even which there isn't a single false truth claim.
Your post, on the other hand, has a couple of false claims, but it clearly isn't misinformation. Unless it's really good and you have me fooled.
By the way, the 404 isn't really the guardians fault, InfluenceMap seems to have (re)moved the report.
