But seriously, let's put these reactions in perspective. Supposs the same was revealed the other way, about a US company having ties to the US government investing in Russian technology. We wouldn't bat an eye. This hysteria about Russian collusion makes us waste our energy and attention which is necessary to pay attention to the real issues (which I list below.)
I am not surprised that a Russian billionaire has ties to Putin, or invested in US companies. His company has since sold his stake and moved on, and nothing scary happened.
Compared to what the USA does on a regular basis, Russia is a pretty good actor when it comes to external dealings.
What's much more worrying is internal Russia policies. I personally know some people who started VKontakte (the Russian facebooj). They all sold their stake or were later pressured to do so by the Russian government after refusing to cooperate with the equivalent of the FBI's NSL + gag orders. and of course the Mail.ru conglomerate wanted to take it over. Not easy to maitain a business in Russia.
(Note: the US has just as much spying and NSL+gag orders but far, far greater freedom of speech and property protections so we don't feel it as much.)
But outside? Look US firms regularly make investments in companies around the world. The actual influence comes not from investment but from things like:
The CIA approaching VK founder and developers hoping to install backdoors in Telegram
Microsoft Windows new versions phoning home or cooperating with the CIA. There is a reason many nations including Russia have built and are now promoting ther own operating systems instead of Windows.
It's just so sloppy to talk about "ties" to something. The hysteria cheapens the impact ahen something real happens. Like backdoors and hacking.
