Xian, it is absolutely a problem, if the wording is going to be so unclear.
The wording is not unclear. I am merely surmising that the song may be deleted at some point. There is plenty of anecdotal evidence pointing to the fact that uploaded songs are not deleted (at least not immediately). In fact, there is the distinct poissibility that "delete" was the wrong word to begin with, and that Apple has changed things to more accurately reflect what is happening. In other words, they've corrected the problem you didn't know you had, and that correction is now what you take issue with. Again, there is no problem here, per se.
Whether or not it's technically deleted from Apple's servers I couldn't care less. "Hide" certainly implies it's still going to be in my iTunes Match account, the same way I can "hide" an app in my iTunes store Purchased list but later I can unhide it. Even it was still technically on the server after the old kind of "deleting," only I should have access to it, so it may as well be deleted.
Who says anyone other than you has access? You are assuming here. More importantly, did you read the Terms of Service? Is there not a clause that says whatever you upload to Apple's servers becomes their property? Welcome to "the cloud." What's yours is not yours once uploaded.
a more logical path would be to reinstate the old wording, which makes far more sense for non-purchased items.
It would not be logical if Apple is not deleting your songs. If they are, indeed, hiding them, "hide" is not only the more logical word-choice, it is the more accurate one as well.
And Xian, the original question is about iTunes Match, not iCloud. As you should be able to see from the image I included above, the new delete dialog box says "Hide in iCloud" not "Hide in iTunes Match." That is very confusing, and another thing Apple really ought to change.
What Annabelle wrote, and the piece to which I responded, was "Where can I manage my icloud space for iTunesMatch?" So yes, this is a question about iCloud (among other things). My answer was correct: you cannot manage the iTunes Match portion of iCloud (it is not like, say, Pages in that respect). Your confusion may stem from thinking of "iTunes Match" as some sort of "thing" rather than just a subscription. Put differently, everything you do with Apple in the cloud falls under the rubric of "iCloud." "iTunes Match" is simply a service to pair your songs up to Apple's songs, and upload unpaired songs to a non-user-managed portion of iCloud as a convenience.
I have verifed that "hiding" the tracks seems to take them out of the count for iTunes Match
Yes, as we said.
