This is empirically false. Video games have shipped with highly-intrusive rootkits and malware disguised as DRM for years, and it tends to be worse on the higher-end products, vs the shovelware/free-to-play/open-source.
You can find a few counter examples but they never last because the commercial pressure is too high, the obvious example is Sony, are they still deploying rootkits? Lenovo is another example that has started cleaning up its act.
Would these companies change if their only source of funds was the malware? I don't think so.
