i personally believe those designs should be open source anyways. After what many mining companies have done to maximize their profits at the expense of the miner.. i dont really see it as stealing. Did they make their own actual boards? The case appears to be yes.. and this is likely to be the same company/families sharing the plans and making a new company. Its not exactly secret technology by any means.
it is not the same people - the guy who developed them is the one that originally stated they stole his programming, his design and basically copy/pasted his sale thread - the original poster was banned from the forums because of the plagiarism even.
