Gold Apollo probably have no plays/connection in this, they were as dumbfounded as the other company that had their stuff being used as bomb, things like Casio watch or Sharp sensor, both of which were very popular with bomb maker.
There issue here is, for Gold Apollo to actually get involved, that would mean they are supplying those pagers to Hezbollah direct, that's mean they are violating department of commerce sanction, unless they don't care about US market, they aren't dumb enough to violate US sanction.
Another issue is, if they were the one that put the explosive in those pagers, then they will have to ship it to either Israel or a third-party country, that extended the risk of getting caught with smuggling explosive.
Usually things like this, Mossad bought these pagers using a shill and then ship it to them and "modify them" and then deal with Hezbollah. The issue I read that BAC is actually an empty address on an apartment building, that make BAC looks a lot like the Israeli shill company that bought the pager and send them somewhere.
