Sorry, but this article seems a lot more like a rant than something well thought out.
I honestly don't believe that you played any of the Final Fantasy 'ports' or remakes that you're criticizing. The fact that you can tout the Ocarina of Time remake as anything other that an enhanced port 'done right' compared to something like the DS remake of Final Fantasy IV, is kinda sickening. By the way, Ocarina of Time has been out since the Nintendo 64, and it's been 'ported' with minimal changes and no additions to both the Gamecube, the Wii through VC, (correct me if I'm wrong here,) WiiU vc, and the 3DS. With exception to the normal DS that's just about every system that could feasibly handle the game since it's release. The 3DS which needed a sales boost only got a paint job'd Ocarina of Time.
Ports are not remakes. Ports take a lot less effort, as it's more or less just moving a game to another system. I can not criticize ports, and you shouldn't either. Ports enable companies to get that tiny bit of extra cash that they need in an every increasingly expensive industry. Games aren't cheap to make, these ports are functioning as more than just extra cash to line the coffers of the videogame company giants. They help give companies larger budgets on new triple A titles, like Final Fantasy XV and Kingdom Hearts 3.
These are games I play once every few years anyways. I'm going to play them regardless, but the fact that each time I play them I get something new out of the experience, such as touched up graphics, new dungeons, increased difficulty, and new super-bosses, it seems like a win-win to me. Actual new content and the ability to play these games legitimately and optimized for my phone is great.
Finally, you made some mistakes: Final Fantasy IV wasn't for the Famicom, it was for the Super Famicom. Also if you're trying to make a point about how many times it was released, you missed a few. It was also released for the Wonderswan Color, and the PSP, as well as the 3D version for DS, which is the version on 'Mobile Platforms.'
