I think the broader issue that Roberto is referring to is that Google is an unethical company for the reasons Roberto mentions, and for all the reasons that are agreed upon by privacy advocates today. I personally believe these are legitimate reasons to sever ties with Google. The pertinent question, from this perspective, is rather whether it is practical/feasible for Debian to find an alternative to the services Google provides, and whether Debian can survive without Google sponsorship.
I also don't think severing ties with Google the company has any bearing on whether individual contributors to Debian who are employed by Google and contributing to Debian under Google's capacity should be banned/shunned/whatever. I think Google employees should be allowed to make contributions to improve Debian. I think this in itself is categorically different from large-scale big corporate sponsorship (e.g., DebConf) or large-scale infrastructure dependency on unethical Big Tech companies (e.g., GCP).
