www.eea.europa.eu/publications... This is a whole chapter (pdf) on how tobacco industry manipulated research, eg denying effects of second hand smoke. Need more? Google it, there are loads of articles showing how lobbyists influence (the perception of) science. It's ghastly.

Studies like this: www.theguardian.com/environment/... Shell and Exxon didn't exactly openly share their findings...

Which is not remotely close to “The gobbmint is hiding s3cr3t pr00f vaxxxxxinez are t3h evulz!“ Among other things, thousands of papers showing the effects of tobacco and global warming were widely distributed in peer-reviewed journals.

The lobbyists aim was to gin up “controversy” and “disagreement”. But the pro-plague anti-vaxxers have no “dissenting views” or “complexity”. The issue has no “controversy”. You might as well say Big Vacuum is suppressing the TRVTH about the subluminous ether.
