just don't remember it being a problem until Lewis has had a dominant car,red bull won 4 championships on the bounce
The underlying degree of dominance is different.
And the options to catch up are a lot more limited ...
(What ever the fxxk that is) but they were good for the sport according to Bernie now they or threatening to walk because they have not won for 1 season
Whatever sour grapes may be at work with regard to Red Bull's position there is also a grim logic.
And it doesn't come down to not having won for a season but is also down to them foreseeing a lack of opportunity to compete for another world championship as things stand.
Their fundamental problem is that they don't have access to a top line engine. In the past a team could take a risk with another less established engine supplier but the situation in F1 is that there is no practical means of competing and developing the engine performance. At the same time the power units (let's not call them just 'engines') are more complicated and more expensive.
Any team looking at a new engine supplier is going to take one look at the trap Honda and McLaren are in and think again.
At the same time the only two desirable engines are owned and controlled by works teams - and they're always going to be looking at maintaining their competitive advantage so have a disincentive to supply engines to other teams on equitable terms.
So why should Red Bull stay on?
If they pay to develop their own engine then unless by some magic it works right out of the box (unlikely) they end up unable to sort it and unable to compete.
Or they can pay their competitors for an engine that will be slightly lower spec. So they basically start with a handicap and at the same time they subsidise their competion.
F1 is in a very bad place right now.
