Jew here. I wouldn't be offended. I'd thank the person, then find someone who could use it.

And if the person knew I kept kosher but still offered the bacon, I would laugh it off and then donate it.

Being easily-offendable is not a virtue. Being gracious is.

If the gift was specifically chosen for the individual, yeah, I can see being offended. In my experience, once companies reach a certain size, gifts are purchased and given in a one-size-fits-all manner. Inconsiderate, perhaps, but likely not intended to offend.

It was a team of 7. Including the two founders.

If you work for a company that has "reached a certain size", you should be aware that you'll have groups of people that make certain one-size-fits-all gifts inappropriate. Like pork products or alcohol in any country with a non-trivial number of Jews and Muslims.
