I was, at first, a bit concerned. But I know I myself don't use the 100 downloads per day anymore on Amazon.
I am not going to change what I do or don't download. From what's said, you get the warning email before they do anything, and if it did get to that point I get a warning, then I will become more concerned. I just know Amazon is one of the most used, again because of offering subscriptions to many other providers like Paramount+ and many more.
I don't even see myself having money to buy subscriptions to many other providers. It's all I can do to be part of Prime, and initially it was for the free and sometime faster shipping.
I then took an interest in the movies and shows. They took my interest away from watching on a streaming device due to their stupid additional charge to remove ads when initially there were never ads.
They may find that some people would stop downloading if they removed the ads. But it seems most providers feel they need that extra money, and we all know Amazon surely is not in need of the extra money.
I sadly have to deal with ads on Peacock unless I use streamfab to download, the Netflix I have access to is the ad-free version.
So, if/when I stream, the first provider I go to is Netflix because of no ads. When I did watch Peacock, the ads did not seem like there were a huge amount, like if you watch the movie from a standard TV channel. As well as most standard channels, edit/cut the movies to fit to certain so-called time restraints, etc. You're even better watching on Tubi or Pluto, etc., as they don't seem to edit/cut the movies, although some have more ads than it would seem they need. I liked Nosey app when I first heard of it, as I was a fan of certain shows they had. Nosey had its times, there were ads like almost every 10 minutes, if not more. Nosey has expanded and has even more stuff. Finally, they seemed to have cut back on ads. And there were 1 or 2 ways to download, even from Nosey (with no ads). And they seem to have put more on YouTube, and SF can download, than from YouTube.
For those concerned or really received these notices, and if they are real, all you can do is take breaks. Everyone thinks they need to download terabytes of programs and movies in as short of time as possible, and many providers keep stuff for months before it goes away. And yes, also if it's real, it will just make more turn to torrents and other means and skip SF altogether. Look in the right places, and you can most likely get at least 96% to 98% via other means.(Sadly, I don't see the Netflix 4K as much as I used to, but there was a time they were available) I still try to stay away from torrents as much as possible, even though I have access to VPN's because in the US, they snag you fast for torrenting popular movies or TV shows.
And YES Amazon lets you download with their app, there is even an app in Microsoft's Store on Windows 11, but it saves it, of course encrypted, I surely hope they are not focusing on those people who do it that way. I never tried from the website to the computer.
And you probably guessed I am not a fan of many ads or commercials. When watching TV shows on cable, I use their DVR to record and can then skip past the commercials.
