The main issue is how badly it is presented.
1) The blue is wrong. Just way off. I mean, it is not our blue...
2) It looks childish and plain.
3) White feels like our predominant color, when it fact it is our 4th.
4) The black color feels insignificant. We're nerazzuri, black&blue, not biancazzuri.
5) The lack of gold. That's the biggest turn off, as it makes you feel that this has nothing to do with Inter.
6) Our logo was badass and several clubs were actually trying to copy it somehow (there was
this case in Greece for example recently that people called an Inter ripoff. Their previous one was just a diagonal black stripe with the names on the bottom]
7) The timing for this is awful. There are countless of rumours of Suning being in a bad position and willing to sell for the right price, so them making a brand change like this despite the uncertainty, in a period where basic payments are postponed and [free] transfer activity is muted, it just feels wrong to release this.
8) The communication was bad, there was no real research conducted and Inter fans were not asked. We are a community of fans. We have season ticket holders, at least had until this season. We have Inter Club members for decades now. Under this management we have created a Membership scheme which counts tens of thousands of Inter fans all over the world. None of them were asked to give a perspective here.
9) The logo itself may not look terrible on clothing material, especially if the colors displayed by Inter's management are not respected. If this is our crest's color from now on, it's a failure of epic proportions.
10) The worst part of it all is that once again, Suning is trying to rip off Juventus, who themselves are on a downtrend. It's like following the Titanic...
