Everything about Silcon Valley business is parasitic.

Start with their massive data collection which is being used to undermine our Democracy and other places around the world. They've created the greatest weapon of all time, and take no responsibility for it.

And extend that to their generally parasitic mindset that if you come up with something just clever enough (even if breaks laws), and pour enough capital on it (UBER, AirB&B), then you'll just end up getting away with it while maybe paying a fine which you can easily pay from the riches gained from the aforementioned data mining.

"Move fast and break things"

"Fake it till you make it"

"It's easier to ask forgiveness than permission."

Parasites.

At least the telecoms install and take care of their communications network (sometimes), though I'm not a fan of them either.
