Use an online service that's new enough and small enough and it might not be compromised, but the moment it gets popular men with guns and national security letters with gag orders will show up to install hardware on their prem, take over entire offices, or just demand reports.
VPNs and secure DNS services aren't there to keep your data from the NSA, ICE, or even the police. They are useful for keeping your ISP from selling your browsing history to anyone willing to pay them (https://www.mitnicksecurity.com/in-the-news/republicans-just...). It'll help keep a little of what you do online away from data brokers, keep your ISP from sending you DMCA notices, and not much else.
However, it's not at all the reality of a vast swath of other countries (or, at least, not yet; see Chat Control v2). The US is particularly foul (and effective) when it comes to this practice, but anything outside of US jurisdiction that doesn't have an office in the US can't be touched by laws like these, and the laws of most other countries tend to be significantly less invasive than American ones when it comes to data interception and the practices surrounding it.
they arent gods. some people actually have moral standards and dont just do whatever a foreign agency wants them to do
Big tech services are less private than you think but almost every provider who cares about privacy is safer than you expect. Most of the people who work there are committed to their mission, and if they ever get a gag order someone will leak it in no time because they know exactly how to do it without exposing their identity.
When it’s a hostile environment entirely, they hack and do secret operations and bribe.
