Sadly for the people they are "alienating" they don't really matter that much for the success of the franchise in the future. And people in the area who already like baseball will still probably continue to like it even if they grumble and groan about a logo change.
By the way I don't really like the "3 key themes" very much but if we really want to go there:
1) Connect with the city of Cleveland - I think you'd be inflating the significance of bridge guardians to think that people think of them when they think of Cleveland today. I'm not from Cleveland but I asked people about them and they were kind of like huh.
2) Preserve our rich baseball history - I don't even get this one. It's not going anywhere but I don't know why we need to go full cryogenics on our current branding especially when the FO has taken the position that it's a mistake. I think those that don't believe it's a mistake will appreciate something similar to Guardians but:
a) They have little to do with baseball history per se, apart from proximity to stadium
b) Failed franchise or not, Spiders were one of the first baseball teams. Not what I'd be emphasizing at all but it's kind of cool.
3) Unite the community - Spiders are kind of universal. Baseball has a problem with young and black people (look at NFL/NBA in contrast) and Guardians would be furthering that trend. I think more in this demographic are interested in looking forward rather than backward at that old, white part of the past. The flexibility and possibilities with Spiders makes the historical origin kind of irrelevant.
