It's not really about nationalism. It's about other nations (especially those likely to face serious problems in the near future) having leverage over you, which they could use to serve their own interests at the expense of yours. Look at how Huawei was essentially destroyed in Europe, even though it was growing by double digits each year. This happened because they were blocked from accessing Google services by U.S. government. You can't just easily switch to an alternative when U.S. software monopolies dominate the market. Replacing them would take a lot of time and money. Ultimately, this is about national security and geopolitical concerns.
