Let's do a little math...
As of this exact moment, YouTube shows the video has having 3,626,654 views. Let's assume this means that many people have watched the entire 4 hours, 5 minutes, and 38 seconds of it (probably inaccurate, but it's what we've got). That comes out to 14,847,118.51 hours of eyes watching this video about the Starcruiser's failure.
The Starcruiser itself operated from March 1, 2022 to September 30, 2023, which is 578 days, or 289 possible 'departure' days (though we know that it was only operating 4 days a week toward the end). Assuming an average occupancy of 4 people per room (which is higher than reality), with 25 hours and 15 minutes of 'entertainment' time per trip (per the numbers in the video), that comes out to 29,189 hours of people being entertained on the Starcruiser.
In less than 1 week, this video has been consumed over 500 times more than the Starcruiser did during its entire operational lifespan. And of course, that says nothing of the number of people who have watched this video compared to the number who experienced the attraction itself.
While I'm sure the number of people willing to watch a 4+ hour YouTube video about a defunct tourist attraction is somewhat limited, it appears that this is reaching a fairly wide audience that likely includes a lot more mainstream viewers than Disney news typically garners. One has to wonder whether it will have any effect on Disney's business philosophies that have been so clearly called out in it, or at the very least, whether it will make customers more skeptical of the practices already in place.
