Is it mortally ok or do Apple find them secretly?
Hmmm - I really don't think that morality and "getting caught" are two sides of the same coin...
...and do you really need to be told that telling a lie for financial gain is (a) immoral or (b) illegal?
Although, frankly, there are greater evils in the world and if you want to take the very small risk of getting caught then I'm not going to cast the first stone. The whole Pro bundle for $200 is rather tempting and ISTR some moral systems have a thing or two to say about leading people into temptation... Practically speaking, if you're using it for professional/commercial work then you should be professional and pay for what you use (both morally and risk-wise) but if it's for personal use, I doubt Apple would give a wet slap so it's down to you and your conscience.
Not at all. Not being eligible, but taking advantage of an offer is like switching price tags on items in a store.
No, it's really not. Dishonest, yes. Breach of contract? maybe (software license agreements have got so ridiculous and one-sided that they long since abandoned any moral high ground, but, hey, two wrongs don't make a right).
But... equivalent to taking physical goods without paying for them? Nope.
If a shopkeeper has 10 leather jackets and somebody steals one (or switch tags with a cheap item) then they only have 9 leather jackets left to sell. Now, you
can try and contrive situations where the shopkeeper loses a full-price sale as a result (it's not like the shoplifter was ever going to pay full price) but they're out of pocket by the wholesale cost of one jacket.
For a digital sale - the marginal cost of supplying a copy are somewhere between negligible and zero. if someone obtains an illicit copy then the
only significant loss is the hypothetical possibility that the recipient would otherwise have paid for it - which is a long way from certain. If they've paid
any money for it then you've most likely made a profit on the transaction.
In the case of Apple's $200 Pro apps education bundle, they'll have collected an awful lot of $200s from people who, otherwise,
at best would just have paid $200-$300 for one of the apps or, more likely, just made do with GarageBand and iMovie (or subscribed to Adobe CS because they didn't learn their 12x table). They're not taking any real hit and probably couldn't care less if a proportion of recipients aren't bone fide students.
That doesn't mean to say that it's not
wrong to be dishonest - and unprofessional/risky for commercial use - or that large-scale organised piracy can't harm the industry - but, realistically, unless you're re-distributing illicit copies on a significant scale, it's a victimless crime (in a way that shoplifting and "oh, they'll just claim on insurance"
aren't victimless)... and over-stating it as tantamount to theft has its own negative consequences (see all the copyright holders' groups using the "every single illicit copy is a lost full-price sale" fallacy to concoct ludicrous figures for 'losses' to support their lobbying for increasingly stringent copyright laws and to justify obstructive DRM).
