I honestly dislike it that Mans and Benjamin spoke out about "Europe hating on Sweden in Eurovision" - That's simply not true.
I can understand that it must have been a tough moment for Benjamin to hear the audience go wild when Sweden "only" got 21 pts from the public in 2018. It wasn't hatred towards Sweden, though. It was a heavy reaction towards the juries which are usually over-estimating Swedish entries in Eurovision. They ranked him #2 in a very competitive year even though his song was generic.
He wouldn't have got that reaction if he got 153 pts from the juries and 121 pts from the public instead.
Of course, Sweden is a powerhouse in Sweden and rightfully so since they are very competitive, treat Melodifestivalen well and come up with a very entertaining show but I think that the juries are after lured by the great performances and forget to rank the song (e.g. "Unstoppable" wasn't good at all either).
When it comes to Mans, he shouldn't feel bitter at all. He won ESC and "Heroes" was a mosnter hit across Europe - We (fans) are just tired that a) our choice didn't win thanks to the juries over-estimating Sweden again and b) we had to hear "Heroes" and see Mans in almost all editions afterwards (2016 as a host and performance, 2017 as part of cameos, 2019 when Conchita performed "Heroes" and Mans performed "Fuego"), 2020 when ESC cancelled and we got a on-tape performance of Mans/Heroes A-G-A-I-N, 2021 when Mans performed as part of the "roof performance". ).
All in all, Mans popped up/performed in every year from 2015 to 2021 apart from 2018 when the contest was hosted by Portugal and in that year, the hosts sang "Euphoria" - another Swedish winning entry.
I just think that we fans (and that's only us fans because the general public don't care about it at all) just feel oversaturated when it comes to "Hereos" and "Euphoria" and even "Waterloo".
We don't need to hear them in every ESC edition, either.
Loreen, however, came back with another great performance and "Tattoo" (even though it wasn't as great as "Euphoria") had "international hit/ESC winner" written all over it.
"Revolution", however, is simply generic and flat - and it's not as good as "Heroes", imo - even the staging (whilst still being ambitious) isn't great either (way too dark for my liking)
So no, Europe doesn't "hate Sweden because they are too successful" - Sweden can win ESC every 5 years, imo, if the material is there - but we are just fed up being served generic to good material which are praised by the juries - making our televoting winners lose (Il Volo, Käärjä); and it's just tiring to see Mans in 8/9 out of 10 editions in the past decade.
