> GDPR is a big block towards technological improvement.

It's exactly the opposite.

It forces technology to be developed in a way that protects human rights (specifically the right to privacy).

Innovation is not automatically good if you're innovating in the wrong direction. Think of it as a vector, not a scalar.

I was anti-Brexit when it happened, but am beginning to see the wisdom of it.

It was already non-invasive. I, as a conscious human being browse a website, use their (potentially free) services. The website can of course put a cookie and track me. If I'm really paranoid I could block cookies etc but regardless, no one forces me to use their website.

If someone pointed a gun and forced me to go to a website, enter my personal data and give my data to trackers that would be something else (still not website's fault but anyway).

Who is deciding what is the wrong and good direction to innovate in for everybody else?

Apparently some politicians in EU who has a grudge against US-based tech companies.

"Hey Google and Facebook is doing so well let's make harder for everyone using their services."

I neither have sympathy for those companies and never been to US, but adter all these GDPR regulations I actually started to sympathize.
