When manufacturers do stuff I disagree with, not always political, the easiest thing I can do is to stop supporting them with my money.
In the early 80's GM screwed our family hard with the faulty diesels then refused to stand behind their warranties. No one in our family has owned a GM vehicle, used or new, since. In 1982 dollars it cost my dad three years and $11k in legal fees to beat GM and force them to honor their written warranties. That 11K was never recouped but he did the right thing standing up for the little guy.
We stopped supporting Nike with the first Kaepernick ad. We have avoided Exxon, to the best of our ability, since the Valdez fiasco and we stopped shopping at Target as well. I also stopped buying from Sears when they stopped honoring their Craftsman tool warranty and failed to make good on two Kenmore appliance extended warranties. These issues required us to hire a lawyer. We won but the legal fees were never recvered. We will also never own any newer Mercedes-Benz after they tried to screw us on a CPO warranty, we won that legal battle too but the legal fees to do so were not recovered. We have also stopped supporting P&G/Gillette, to the best of our abilities, as well. Thanks to their ad campaign from last year I discovered how wonderful and affordable Harry's razors are. Sometimes these companies actually do me a favor by forcing me to re-think why I am supporting them.
We also dropped cable & network TV almost 14 years ago & well before Netflix, Hulu or Amazon Prime even existed.... We stopped supporting professional football, basketball & baseball too.
There are a number of other companies we choose not to support but it is not usually based on politics. Sometimes companies are just scumbags who treat their customers like crap.
