Countries can and have under the name of "digital services tax". Generally the rates are low and often only cover a subset of things. The US and tech giants have historically pushed back hard on them. This is a reasonably up to date link to the situation in Europe https://taxfoundation.org/data/all/eu/digital-tax-europe-202... Keep in mind many of those are proposed and not implemented.
The real threat to the US IMO is losing marketshare. The stock market has gotten beat up but most of the real pain for the average person is still off in the horizon. Anti-US sentiment is growing quickly, if we enter a full blown global recession/depression I think it could be a real catalyst for large sudden shifts away from US tech companies.
