The pre-built ships are not "pay to win" as the OP suggests and Belluler News cast tries to mislead their audience on. There is a steep learning curve for new players just starting Elite Dangerous, and without the fan supported websites those new players would be undoubtingly lost because those fans supported websites connect information to the players e.g. where to find modules, ship hulls, trading routes, etc. These are all quality-of-life improvements for Elite Dangerous players, and Frontier should continue to support these sites. It is also misleading to say "end game" when there is no "end game" except what players individually deicide is their "end game" based or dirven towards what their chosen playstyle or interest are throughout the time playing Elite Dangerous.
The argument that pre-built means the purchasing player did not have to grind for credits or materials is selfish-minded. These pre-built ships offer templated road maps on starting ship builds and those pre-built ship modules are not interchangeable to any other ship. Once their replaced, their gone forever, no refund. They're only saving a few million credits - at most - and about a full day's worth of game time since there are numerous fans supported websites that offer "Road to Riches" avenues to earn credits. IF you want to argue they did not earn the credits - well, so what!?! Or the different sites on how to obtain or unlock specific modules. The person would still have to do the whole engineering unlocks and material farming like the rest of the CMDRs who want to get more out of their ships. Pre-built ships do not short cut this.
There are only three pre-built ships worth the ARX after reviewing the choices: Python mk2, Chieftain, and the DBX (actually the DBX needs v1 5A FSD). All those pre-built ships offer is an introductory ship build(s) for BH or CZ, Anti-Thargoid, and exploration, exobiology, and jumping around the "Bubble" little easier. That's it, nothing more, and everything someone could do without purchasing a pre-built ship. There is no "pay to win" there and offering some shortcuts e.g. the Chieftain's r5 Dirty Drive engineering and their two (2) guardian gauss cannons the anti-guardian zone resistance is trivial. Again, no "pay to win" there too.
I have help over 6+ new players just beginning Elite Dangerous. The initial to-dos jump starting them was a couple team BH/Assassination missions while they chilled in their Sidewinder at the space port to collect the mission credit rewards to get transition into a DBX and 5A FSD (moving modules from Sidewinder over). Then, introduce them to the material farming locations for the engineering materials required to purchase the v1 5A FSD. Then, one quick FC run out to Guardian Structures for them to gather the blueprint and guardian materials to unlock their gFSD Booster, and once everything is complete, their "Quality of Life" starting experience improved. You could accomplish these tasks within 2 or 3 game sessions. The pre-build DBX essentially does the same thing that I have done for other players, and my near identical assistance to those new players it is by far, nowhere near any "pay to win" advantage. There are far more activities and prerequisites they'll need to complete to prepare for those CZ, Hazardous BH, Assassination Missions, Cargo Trucking, Mining, etc. type activities.
As a Veteran player, I see nothing wrong offering introductory ship build as pre-built ships. And I would not call any of the pre-built ships a "pay to win" scenario. Time and grind as an argument is a poor one since the actual time is trivial and their pre-built ship modules are not interchangeable to other ships. For me, opening the option for pre-built ships means their able to wing up sooner than later to do group activities with a starter ship while they progress along unlocking reputation for Federal or Imperial ships, unlocking engineers, earning Badges, and the whole engineering gambit attached to ship building.
Remember, the fan supported sites help make Elite Dangerous playable. The optional pre-built ships have the same purpose that enables Frontier to assist new players without breaking the game, as their pre-built ships are basic builds.
