Seriously, why do you report on this? Ordinary users should not install alpha versions. Period. If you don't mind losing data and want to participate in testing, sure, why not. Beta is a safer option if you want an access into their testing program and is easier to install (I guess that's on purpose to ensure there is higher cost of entry into the riskier alpha program). However, ordinary consumers should use production builds unless there is a serious issue that needs fixing ASAP.
