Every time I hear this, the number seems to go up. Please provide a citation for that number. You are saying all tech workers in the US? There's no way that is possible. You realize that there is a larger tech work force in the US than just Silicon Valley right?
1. It is controversial to employees who support Trump.
2. It is controversial to investors who support Trump.
3. It is controversial to clients who support Trump, and now might stop using AirBnB.
4. They are taking public stance against the president of the US who is known to have a vindictive streak (and his businesses are their competition). How motivated will Trump be to sign legislation that hurts AirBnB?
Do you think this is an easy decision?
Like gay rights in the 2010s (which no company would touch with a ten-feet pole in the seventies and eighties, but they make grandiose stands now that it's safe except in some backwater redneck communities), it's just the fashionable thing to do.
It's not even like the Vietnam war protests in the 60s, when mostly the young and alternative press were in favor and it was an actual risk.
Now you're on the side with mainstream press, corporate giants, most of Hollywood and show biz (even country acts), major TV channels, etc.
Is it controversial to anyone else? Even someone who supports Trump's executive order may consider it reasonable that refugees should be housed somewhere.
What I consider controversial is backing a candidate who actively helped create the current Middle-East crises, supporting the first Iraq War and then the overthrow of the Syrian government.
I'm glad Airbnb is doing this, and I think in the future it will be seen as an important show of goodwill. But the company is certainly taking a risk.
It's as much a gesture to make themselves and their own employees feel good. With something on the order of 40% of tech workers born outside of the United States who may be really scared right now, they may actually genuinely care about their coworkers! And this has the potential to kind of kill the whole tech industry in the US.
