I think IEO is good and more reliable than ICO. In IEO there will be fewer scams. But I dont like that in IEO only exchanges and investors and start-ups can earn, and theres no place for bounty hunters.
And why is that bad. The only reason for bounties is to help spread the word about a project. If a project already gets advertising through an exchange, then there is potentially no need for bounty.
It should be seen as a positive that IEOs are likely better for investors since they are actually spending money on the project.
They say it bad cause they are thinking that IEO will be just the same for ICO and they also put in their mind that, of what it happens to ICO will similarly happen again into IEO projects. I hope they weren't wrong, in fact, IEO hasn't proved anything this time that is why they should give their best and so investors will look into them.
