Am Turkish, and not really. There is no evidence of Turkey caring about what the individual citizens visit (except in case of a crime investigation etc.) Bans in Turkey works like this: Turkey sees something they don't like on the Internet, Turkey reaches the company / individuals behind it (they can be anywhere in the world) and tells them "take it down or we will block your access to Turkish citizens and you'll lose revenue / traffic". If the site owners comply nothing happens. If site owners refuse for any reason, they block the site so it is not accessible from Turkey. In the older days, they used to do it through DNS but it was easy to circumvent. Now they use other methods so changing your DNS isn't enough, but a VPN works just fine.
This was also the case before https wasn't as common BTW. Turkey either didn't have the technical capability to block individual pages (even back then) or they were seeking to punish the site by blocking access in whole.
A site like wikipedia values integrity more so they don't take pages down without good reason. But companies seeing Turkish citizens as a revenue source generally comply. If you browse Twitter in Turkey, it is common to see tweets where it just says something like "this tweet is blocked in your country" - Turkey reaches twitter to mark the tweet invisible and that individual tweet goes away. IIRC it also applies to entire profiles - I'm not a frequent twitter user but I remember seeing entire profiles blocked by country.
