The last time something like this came up, I argued that this is part of the cost of doing business-- You can't just take something apart and put it back together and expect it to go perfectly every time. Look up "entropy".
Unfortunately, I (and the others sharing my viewpoint) got attacked by the legal eagles, especially some rather unforgiving European posters here.
But if the lens had fungus bad enough that it was in between two cemented elements, then I can't believe that the surface of those two elements wasn't also damaged-- and was probably the reason the lens shattered, due to the uneven heating. It's possible he should have used a different technique-- I'm not an expert in glass, particularly optics. But the only way the fungus could get in there is by either eating the cement, or the glass, or the original cementing was done badly.
Regardless, that lens was, at best, [Near Mint+++].
Move on, decide whether it's worth a 40 year friendship (Hint: It isn't. The number of people I can still call friend after 30 years is very small, and over 40, nonexistant), and look for a suitable donor lens.
