Kind of ridiculous.
Rather than a dumb "web" version, they should revisit their pricing model. Their current monthly subscription model may work for professional users, but for occasional users it just isn't feasible. $20 per month if you only need it a couple of times a year is just too much.
Sure, photoshop has more capability than Gimp, but for the occasional scale or cleanup job it just isn't needed, and $20 is not reasonable for the typical home user.
Web based software is just not something I am ever going to use, even if it is free. Nor is subscription based software.
Software needs to be local, installed and it needs to be in native compiled binaries. The trend towards making absolutely everything web based needs to end.
