Recode doesn't cover the other side of the fence, but a number of other publications have noted that according to FEC filings, one of the president's few Silicon Valley backers from 2016 - Facebook director and NZ citizen Peter Thiel - has not donated a penny to Trump this cycle. Thiel hasn't commented. The rumour mill holds the billionaire became disillusioned with the president's handling of the Covid crisis.
Elsewhere, Trump gets a smattering of support. Apple vice president and associate general counsel Douglas Vetter has donated US$208,000 to organisations including the Trump Victory Fund. And former Sun Microsystems CEO has chipped in $111,200.
Silicon Valley's highest-profile Republicans, Oracle founder Larry Ellison and former HP boss Meg Whitman, both boycotted Trump in 2016 and have kept their chequebooks in their pockets this year, too - at least where Republicans are concerned. Whitman has donated a little over US$700,000 to pro-Biden funds.
