The Writers Guild, of which I am a 30 year member, is taking on the issue of Product Placement in movies and TV shows. This is not a new practice. It dates back at least to the 1949 Marx Brothers movie, Love Happy. Assuming you made it to the end of that gobbler, you may remember a chase scene near the end involving illuminated advertising signs. Legend has it that they were there because the producers were short of completion bucks. As the story is told, they sold plugs in the movie they wouldn't have been able to otherwise finish. There must be earlier examples.
The Guild has whipped up what they're calling a "white paper" on the practice to provide an overview. This page has a list of links to articles about it and here's a link to a PDF file of the white paper. And I don't know how effective it'll be in calling attention to the problem but they've also put up a webpage called Product Invasion where you can give commands to a subservient Donald Trump. Give it a try. It's pretty funny.
