If that's your personal belief then obviously you're entitled to your opinion, but have you seen any actual evidence that that is the case?
However, after the initial bring-up pains any business which continues to have a problem with the GPDR most likely has a business model directly in conflict with the spirit of the law.
Perhaps, but as you say, what we know now is that there are some initial compliance costs for everyone. If nothing else, we all have to understand the new regulations and our obligations under them, and we will now have to allow for additional subject rights and stronger and more specific documentation and notification obligations, which generally apply retrospectively as well.
I admit that part of my concern here is not specific to the GDPR, but rather to the general practice of creating ever more rules governing businesses. Every time some new regulation comes along, the costs of running a business go up. Not only does that impose some level of overhead on established businesses, it also has a chilling effect on new businesses starting up, and on paths to growth like starting a side business that can expand to something full time and later to take on additional employees. If a new regulation is necessary to achieve some positive effect, then those overheads might be justified as well, but I remain to be convinced that this is the case for most of the new rules and regulations that have come in over the decade or so that I've been doing this now. The GDPR is just the latest example of something perhaps well-intentioned but poorly implemented.
I can't speak for that other person but I've seen lots of evidence to that effect. I look at ~40 companies / year at the moment and a large percentage of those has issues. Usually not because of malice, mostly because of lack of resources or unfamiliarity with regulations.
