Depends on how many people know about it and might interprete it as some kind of association. I would be sceptical to use 88 as a designation, at least in Germany. See 4 or 13 for numbers avoided in other cultures (for non-political reasons).
Well, we're talking motherboards here, I live right next door and had absolutely no idea and it definitely would not affect my purchase of any product numbered 88, living in house number 88 or setting the price of a product (though 89 would obviously be better).
I have no idea why 4 would be special and 13 avoidance is for superstitious people which I'm not one of.
So forgive me if I don't see the problem with the 'Navi 88', in spite of being pretty sensitive to such issues because of what my grandparents went through.
When some kids wanted to do a dance festival under the label 'Tanzen macht frei' I thought it was in pretty bad taste because it clearly intended to be a reference. But just a number is not enough to trigger my sense of indignation.
"Nazi numerology"? How's that a thing? We have already started banning words, so now start banning numbers just because some braindeads use them instead of banned words? Please, stop.
So what? The killer must have wear shoes, so should we ban shoes now as well? I understand what these numbers might mean in some circles, but I just don't follow logic why the rest of us would care. After all, Streisand effect kicks in if we try to limit usage of certain numbers.
And if he was, would you propose Nike stop marketing their shoes? It's probably another US-centric thing I will never understand, like skipping 13th floor or plane seat number.
P.S. we have already derailed this discussion deep off-topic, so I will not continue any longer.
Meanwhile, the 300-unit housing complex next to where I live doesn't have 4 in any of the addresses. The street blocks even go 100, 200, 300, 500, 600...
Seems like their marketing team cared enough about a number.
Neo-Nazi's don't get to claim integers.
