I don’t think that’s a valid explanation. Cam rips have been available for almost every big blockbuster in recent years. A relatively high quality cam rip of Endgame was released just a few days after the film released, and it still became the highest grossing movie of all time. I think the biggest factor in declining numbers for TROS is the mixed to negative word of mouth, from both critics and fans.
A quick example… around one third of IPTV services went off-line for a short while earlier this year due to incidental police raids. That was 50-60 million accounts for IPTV affected alone - not firesticks, not streaming sites, not downloads, nor torrents (all of which are more prevalent and easier to use and find with each passing year).
Plus, like I said, it is not just a problem for TROS - it is for many films released at this time of year.
Endgame was released in April - not around Christmas where money can be tight(er) for many families. If Endgame hadn’t had a quality cam released within days it too, like many other films, would have likely made even more money at the box office.
If you disagree, then fair enough 😃
