Lot of non-cricketers get confused by "wickets". The playing area is the pitch. Wickets are stumps. So, it makes sense to call "outs" outs and it removes the confusing bit.
Some of the comments here do reflect a certain elitism cricketers have about the sport. If you really want to make it popular, you'd simplify the terminology which is what ECB is doing. Some of us just refuse to acknowledge that cricket is NOT an easy sport to get into (unless you are born around people who play it) or even stay into (gear woes, bats are schit!).
Make the terminology clean, make bats easy to ping without extensive preparation, cheaper and better safety gear are some of the things that'd help invite and keep new cricketers.
Kudos to ECB for moving in the right direction.
