So if we’ve agreed with OPs assessment that the problem in the UK is the government attempting to seize more power…how will becoming subjects of yet another government body that is even more powerful and less beholden to the people…help things?

The EU might be better on digital privacy right now, however the emotional winds of the political mob change often and many people in EU government feel differently. The EU is also an aging population of technologically illiterate and immigrant-afraid retirees. I wouldn’t expect much different coming from them in the future.
