Tools are made to make our live easier, even considering that in most of the occasions its use is not essential: think about forks, drills, hammers, ball-pens, whatever you want. In fact, a proof that third party tools are useful to a good bunch of people playing ED, is the fact that most of us are really off that we cannot use INARA, Coriolis, etc.
I don't like strikes, and I don't like having to give up using EDDB or Captain's Log because of a certainly untimely -thinking about the event of Saturday 29th- protest. But I fully understand the arguments of 3rd party tool developers asking for greater support by FDev, and a bit of love for their work. So, although I don't like the strike, I fully support the protest and also kindly ask FDev to positively consider the, mostly, reasonable suggestions and comments made by the OP.
In my opinion, third party tools provide some good solutions for those parts of ED where, right now, there are some problems/weaknesses related to in-game information management and usability. For sure I would prefer to have these problems solved inside ED, but third party tools offer a good compromise (even having to use them from outside the game) to provide a more pleasure game experience for a lot of people, and I'm grateful for it [yesnod]
TL;DR: my full support to the suggestions made by 3rd party developers to FDev.
