As I am still having 7 days to go and that is just a personal blog, I plan on using my free time to do that (would just take 3 - 5 minutes to disable everything if I wanted to by removing GTM and redeploying).
So removing everything is quite easy. It is way more difficult to selectively remove singular features - in this case the DoubleClick integration. As I am not doing that exact step all day (even being a data analyst with a focus on web data), I would have to look, where to configure that exactly. That would take longer.
So be snarky - I don't care, as I am already preparing for GDPR compliance and will have my house in order come May, 25th.
[Edit] Took 12 minutes in the end. Will take some time until caching catches up. Using a incognito instance all good to go regarding the trackers. "Only" the update for the privacy page remains for the weekend to do.
I thought the GDPR required users to opt-in to tracking (if consent is used as the lawful basis for processing), and if they choose not to opt-in, you must disable the tracking while still providing the service. Are you sure just updating your privacy page is enough?
Then there are the requirements to allow users to download or delete their data.
