I think all this talk of lawsuits is pretty silly. Actually, I think most of the complaints about locked bootloaders is pretty ridiculous. How about the people who are writing to carriers and phone manufacturers offer more than just "please unlock the bootloader" or "we're gonna sue" how about offering them reasons to do so, or solutions to whatever problems are causing them to want to lock the bootloaders.
I think two of the bigest reasons they are locking down phones have been mentioned. One is because of all the free tethering people are doing, and 2 is because of the phones they are getting back because people screw up when rooting their phones. I mean just look at all the posts on this forum where people are asking for help because they bricked their phones. Now imagine how many aren't even coming to the forum but are just sending phones back to the manufacturers. Maybe if someone were to suggest that instead of locking down the phone, they use, I guess we could call it, a reverse key, where it is unlocked, but as soon as the phone is rooted it generates a key that lets the manufacturer know its been rooted. Make it so that key can't be changed. If they get the phone back and see its been rooted, then they just tell the phone owner that they are out of luck. I'm not technical enough to know how to make something like this work, but i'm sure there are people who are smart enough to do it. But my point is, if we want things to change we have to start thinking from the other side's point of view and offer them reasons to make changes. Unfortunately the community isn't large enough for a flat out threat to work, so how about trying to work with them. After all, you get more flies with honey than you do with vinegar. Even though I don't really want any flies around.
Read this thread, it gives reasons and solutions to why they should unlock the bootloader. http://bit.ly/esEM1f
The talk about lawsuits is a legit way to get to moto if their is a actual ground for it. Android is hailed as open and it is, until it gets to the manufacturer. This is what makes everyone mad, not so much that it is (in my opinion anyways). I mean, yes i would love for the bootloader to be unlocked just so i could really tweak it and see just what this phone can do but I'll live without it. The think that really ticks me off about it is that every other manufacturer but Moto has (to some degree) unlocked phones.
