Thanks for the link. I guess the morale of it is:
1/ dont’ use unsplash for pic with people in it - and even better: go and buy all pics if possible
2/ don’t use ghost’s widget to grab pics from unslpash if you don’t want GA on your site (download the pic then upload it to your post).
The other big difference with GA is that it is self hosted and so it requires the tech skills, time and a server (nodejs & mongoDB). But, because it’s self hosted, you know exactly what is being collected (looking into the db) as it’s also open source (there is no chance the code also sends the data elsewhere), and so you have a closed loop that provides a robust sense of privacy.
Finally, because it’s self hosted and since the analytics/tracking comes from your domain, it’s less likely to get blocked by add blockers and other browser tools as I’ve heard that the GA data is getting skewed by this more and more.
That’s why I’m not into GA and was negatively surprised to see those cookies show up on my site.
