Ackshully…
The TOS Enterprise, as well as the A, D and E are usually referred to as “The Enterprise”. B and C aren’t on long enough for me to remember if it applied to them as well.
However, the NX-01 was always referred to as “Enterprise”, (without the “The”). It’s like they were making a point of it, too. So I wouldn’t count it with regards to this meme.
So you then have to decide which ones you would count, such as the J, the one in ST:P, whatever came up on Discovery… Or whether you want to consider alternates as distinct.
The last two Dell laptops my work provided me with have little sliders that physically cover the camera. I use them all the time while working from home.
