Apple?
And if these specifics don't satisfy you, we all know that the Department of Defense was heavily involved with Silicon Valley since day 1. I'll wiggle my eyebrows vaguely, but suggestively at this fact, and let the audience draw its own conclusions, about the close relationship that the US Government has with SV tech firms.
I also find your eyebrow-wiggling an egregious rhetorical sin, employed only by those who have nothing more concrete to offer. Do you have anything at all to justify your vague insinuation that all of Silicon Valley is a giant government conspiracy?
Apple-NSA collaboration with PRISM. [2]
USDS & 18F involvement: [3][4]
Secret collaboration on tax burden reduction. (It's a longer word for 'lobbying'. If you think it's not secret, please share with me the minutes from those meetings. If you think it's not collaborative, why do these meetings always result in tax burden reductions for the lobbyists?) [5][6]
2 million dollars in direct campaign contributions, in 2018. It seems that to do business, you need to grease a few palms, eh? [7]
You cannot operate a multi-billion dollar company in the US, and not have close ties with the US government.
Not to mention the large number of congressmen, senators, and government advisers who, among their tens and hundreds of millions of dollars, have large financial stakes in Apple.

A nebulous, ill-defined hand-waved general accusation, with no clear goalposts, that infers that there's an intersection between the company's past or present employees, and past or present employees, executives, or advisers in government, that the company at some point received government seed funding, investments, or government contracts, that secret meetings take place between the company, and the government, that the company is a special contractor for the government, building custom solutions for it, or that the company may be compromised by government meddling.
The beauty of accusing a company of having close ties with its government is that it can mean almost anything you want it to mean.
I'm open to the idea, what evidence would you propose supports this?
Name one.
As for the IP angle, what evidence do you have that Huawei in particular built their 5G, or phones off IP theft? I postulate that as soon as China passes the US in development of new IP, the US will find no shortage of excuses to politically interfere in the market... Just like it is doing now, actually.
