Sniffing the Rigol's internal I2C bus

That's great news. Perhaps they can manage to kill off their sales to hobbyists and students. :-DD It would be nice though if they spent that priority manpower in fixing bugs in their units, first. Rather than letting them languish for half a year or more without being addressed.
And one thing to keep in mind about buying the current (hackable) products: they have numerous known software problems (and likely others not yet known, or less visible... such as broken/missing SCPI). Naturally most will want to take advantage of the fixes, but it won't be surprising if there's a price to pay for that.

This was all inevitable and predicted 6 months ago in this very thread. I'm all for free stuff, but there is just no way a company will ignore this - and you can bet you ass that Agilent is working to stop the hacks published in the other thread here too.

Well, no, as shown by the DS2000/DS2000A, they can't stop the hacks working for owners of the current models without voiding all of the legal, paid-for options - they have to release newer/upgraded models. That was my point.

Really, you think they should not worry about people stealing their products? They should just focus on fixing bugs while their margins are being damaged? That's great logic. |O Rigol is a business, they have to make some money. If they think that working on security is going to protect their bottom line better than fixing bugs then it's OUR fault for pushing them to that by hacking their products. :--
I'm a big fan of altering the function of hardware myself but to act like Rigol should embrace theft because it increases volume on their lowest margin sales and to justify this behavior kinda irritates me. :palm:. Rigol likely depends on the adders beyond base to add profit above likely thin margins. In addition, in a low volume business they have a LOT of non-recurring engineering costs to amortize over the life of the product.
Don't get me wrong. I read this thread every day (and have read every message in every page), and love the work, ingenuity and features that have been unlocked.

There are people who bought a 2072 cum 2200 over an alternative scope (or an old beater off Ebay) just because the hack tipped the balance on their buying decision. I find it hard to equate that to "theft" in this instance. They got some money at least, when the alternative was no money at all from that class of buyer.
The question for Rigol is whether those "bottom feeders" are a valuable enough resource to tolerate their antics, even if they cannibalize the professional market a bit. My bet is it's only a little lost lucre versus containerloads of scopes sold as a direct result of threads like this one. Rigol would be best to grin and bear it all the way to the bank.

This argument has been going on in this forum since 2010 - when the Rigol D1052E was hacked (and Dave published a video about it). Regardless of whatever you think might be best for Rigol to do, the fact of the matter is, they fought against the hacks in 2010 - and they are fighting against the hacks now - just as many of us expected they'd do. And from Rigol's point of view, the stakes are even higher now - with the keygen working not only for DSOs - but other equipment as well.
And just as the hacks of the DS1000E series disrupted bug-fixes and FW releases (and created new bugs), so is it all likely to happen again. But, hey, that's the trade-off - for both us and Rigol.
