Zimbra, violating Open Source terms

Not all pretenders are Open source... This is true for zimbra at least which claims it is open source, but actually I see everythg they r doing is against open source. check this for detailed discussion abt zimbra as open source.
I am still in my battle field working on Zimbra.
We upgraded to the new zimbra version now....
In this new version I found sthg in the code that made my nerves; all variables are written in this format "_158", "_140".
I found this hilarious...
