Take Google Photos for example. Since June 2019, it doesn't sync with Google Drive. You can only see your own photos through their app. Getting them onto a computer you own became really difficult. Google Takeout still lets you export all your photos, but it's a rather clunky, manual process. Twitter makes it hard to get API credentials nowadays, so the API is out of reach for most. Fortunately, I had old ones I could reuse. Reddit's API only returns the last 1000 comments, so it's missing about a decade worth of comments. Many websites just don't offer any API at all.
