Technically, the legalese version is written in plain English. ;) But snark aside, I don't think this plain English version is all that enforceable since it doesn't mention at any point about being a contract that you're agreeing to. IANAL, but I think this is part of why the actual TOS isn't written in "normal English". All the stuff that makes it binding (or is supposed to, anyway) and prevents lawyers from twistin…
TECHNICALLY "plain" means a number of things but most definitions revolve around: "easy to perceive or understand; clear, not decorated or elaborate". By a dictionary definition (a technical one), convoluted legalese is anything but plain English.
