TIP to all new to LR or battling to understand it's because it's so different
Get yourself a LR book; yeah, those old fashion paper things that we read and learn from but I guess the Ebook is the same. Even an old book will help to get the head around the bulk of LR. I used Scott Kelby's.
TIP 2: turn off all other editing programs and work only with LR for a few days; just makes it so much easier to understand. I had to do that; and I gave up several times; but now I would hate to have to go back to bridge/PS or whatever.
Nothing beats a little one to one training
"It feels a lot like extortion, too. (Keep paying or loose [sic] access to all your pictures.) "
Completely untrue. 100% false.
If you stop paying, you still have access to all of your photos and edits and metadata. You cannot do further edits or display your photos on the map.
Perhaps you need to find the proper information before you get so angry.
