You're mixing up a few things. The X-T10 is the entry level version of the X-T1. This was decided by Fuji. They obviously thought that the battery grip is a more advanced feature, suitable only for the flag ship model, so they left out the battery grip contacts. It wasn't the other way round. Fujifilm communicated this more than once. After all, they left out the ISO dial and they added the AUTO switch, a feature obviously more suited for an entry level camera. Technically, both cameras perform on an identical level but the UI is different, which makes all the difference.
And yes, I choose tools based on the factual features they offer. On the X-T1, I needed a battery grip. So even if the X-T10 was already on the market when I bought the X-T1s, I would have still gone for the X-T1 because it features the optional battery grip. Nothing funny about that, but rather rational thinking.
Besides, you're the only one who is arguing in an emotional way. Maybe you should calm down and start discussing in an objective way. Feeling offended because someone is calling your tool entry level is not the correct response.
