It is true and I cannot deny how upset it has made me for the past two years knowing that affordable expansion could exist, but the big guy doesn't allow it to. Village instruments were denied a simple developer license without a reasonable explanation. Other eGPU chassis/slot producers were requested to recall their products.
Zodiac has accurately summed up how the very creators of thunderbolt are stymieing is uptake and accessibility.
Not to mention that Apple is basically the only one to use Thunderbolt on their computers and laptops. PC OEMs have basically abandoned TB this year, from what I can see.
I don't know what Intel's plans were with Thunderbolt, but it's a total failure so far. And when they deliberately prevent eGPU solutions, we can see them as 'the bad guy' with good conscience.
