It's not just Chrome. People need to stop using any Google product.
I agree, that's something we really need to do.
However, the alternatives are very bad.
I was trying to using DuckDuckGo... I just kind find anything there. Have you ever tried to find bitcointalk topics there?
I was trying to find my merit source application. I wrote in DDG "Bitmover bitcointalk.org merit source application"
look at the results:

The result is completely ridiculous, as it has nothing to do with the searched terms.
On the other hand, Google results were amazing. I was able to find all the relevant discussions related to my application, even in other boards. I was able to find people mentioning my application elsewhere.
Until DDG or any other search engine has the minimum
usability , there is no competition to many google products.
There is a lot of competition on Chrome, which is not the best browser. But android is by far the best OS for mobile (cheaper, more customizable, etc) and google is the best search engine... Sadly, Gmail is still the best mail service as well...
I believe proton mail is better than gmail, however it is paid (and not cheap). Hard to compete..
