The idea behind a unique "suffix" is to make it easier for the user to identify the *same* issuer, not for the user to blindly trust "Microsoft".
Once again - this is just not going to work - in the distopian world that this would be creating every single "well known name" is a *scam* and "every unknown name" is something you will have to then look up in order to work out if it is not a scam.
Understand that by *simply not having unique names* the motivation *to scam* has been greatly reduced.
If I see someone creating an Asset called CIYAM - then I create an Asset called CIYAM. Basically if the users get "scared off" all that has happened is that *both* issuers have thrown away 1K NXT (but at least confused Joe didn't bother buying shares in either).
There is simply no "good way to get unique names" (and in fact I think the "aliases" should have been non-unique also as now they are basically "useless tokens" a bit like all those "first bits" addresses that were obtained for 1 satoshi each years ago).
In many countries they have IP *rights* to names so the more Nxt tries to favour this "squatting" and "scamming" the more likely it is going to be *targeted* by authorities.
Other ways of trying to work out trust will be implemented down the track - but if you *allow unique* now then you won't be able to "take it away from the squatters later" (they'll fight you tooth and nail about it).
