One other comment: I'll add that criticism of Trump is not just coming from the "hipster" left. I've noticed, for instance, that the Cato Institute, a very well notable libertarian think tank, is taking a hostile stance towards the Trump EO (https://www.cato.org/). This isn't a surprising stance frankly, but in a nation where politics is often thought of as binary (Cato is sometimes incorrectly generalized in this binary as "right wing"), sometimes the subtle nuances are missed.
But that's human nature. Trump has done an awful lot to raise the ACLU's profile recently and ultimately this will be for a better good.
The ACLU has long been a strong advocate against police abuse (one web link of many: https://action.aclu.org/secure/stop-police-killing-communiti...), and the ACLU is participated in combating opiate abuse that emphasize treatment over jail (example: http://www.aclu-wa.org/story/task-force-issues-ground-breaki...). So while Silicon Valley may be reacting mainly to the executive order, support for the ACLU will help address these issues as well.
