Audible's greatest assault is on my wallet. So many audiobooks on that platform are exorbitantly expensive.
I've been a member since 2005/6 (pre-amazon ownership) and I think my longest recurrent monthly thing.
Audiobooks were historically insanely expensive - I used to borrow massive folders of cassette taps from my library of 'unabridged books' back in the 90s. Staple of my family holidays trapped in a car.
Audible the company was the first/only as far as I'm aware company to work out that audiobooks were the 'premium podcast' and actually bother to sell them at a reasonable rate.
