SAN JOSE, Calif. — Like many in the tech industry, Jeremy Lyons used to think of himself as a relatively apolitical guy.
The only time he had participated in a demonstration before now was in the opening days of Donald Trump's first presidential term, when he joined fellow Google workers walking out of the company's Silicon Valley campus to protest immigration restrictions. Google's co-founder and its chief executive officer joined them.
Last weekend was Lyons' second, also against Trump, but it had a very different feel.
The man directing thousands of marchers with a bullhorn in downtown San Jose on April 5 was another tech worker who would not give his full name for fear of being identified by Trump backers. Marchers were urged not to harass drivers of Tesla vehicles, which have gone from a symbol of Silicon Valley's environmental futurism to a pro-Trump icon. And no tech executives were anywhere to be seen, only months after several had joined Trump at his January inauguration.
To Lyons, 54, the change says as much about what's happened to Silicon Valley over the past quarter-century as it does about the atmosphere of fear surrounding many Trump critics nowadays.
''One of the things I've seen over that time is a shift from a nerdy utopia to a money first, move fast and break things,'' Lyons said.
Political gap seen between tech leaders and their workforce
The tech industry's political allegiances remain divided. But as some in the upper echelons of Silicon Valley began shifting to the right politically, many of the tech industry's everyday workers have remained liberal — but also increasingly nervous and disillusioned. Their mood is in stark contrast to the prominent tech leaders who have embraced a conservative populist ideology.
