It is not about "bragging" or whatever. Nor is it about "bad" or "good".
By funding or promoting the use of Google products, you would be funding litigation and influence such as lobbying to keep poor regulation as it is, if not worse. You would be funding their acquisitions of great tech and startups that might offer a more ethical and/or free technology. You would be funding their poaching of said engineers and valuable hardware intellectual property.
Simply put, it is a counterproductive and an unsustainable practice.
That being said, their amazing engineers, and technical value of their hardware are irrelevant to this community, post and comment. That simply doesn't excuse their entire business model being built on breaches of privacy and other forms of curbing user freedoms.
It does not matter, that’s irrelevant to the lawsuit. Google is not being asked to tank its own software. It is only required to provide freedom and informed choice to users, overcoming the anticompetitive advantage it gives itself by not giving users the informed choice to pick their preferred applications store.
