the time limit bothers me... but what irks me the most is that they are misrepresenting what a server is and how it works... they are NOT "storing a my copy" on their server for 2 years. Their fileserver has 1 and only 1 copy of the file (although backups probably exist elsewhere) which they allow me to download, when I download I do not "consume" it, it is creating a new copy on my machine. They are spinning it as if they are physically storing a copy for me, in order to convince people who are completely ignorant of computers that it is a legitimate thing.
And the money you pay? thats only 2 years downloading, not even perpetual download rights!
so the three issues from worst to least bad:
1. The lie about what is happening to trick people
2. Only 30 days to download it.
3. Paying extra only gets you 2 years.
