The fact that the lids are now attached to the bottle, should not make it more difficult to unscrew them.
However I have the impression that it does for some reason. Or maybe my grip is not what it was ….

I cannot explain the mechanical position, but clearly, increased torque is required to remove the screw threads, which are now split. It is similar to removing two nuts from a bolt with a spacer between the two.

The caps are shorter meaning to apply the same force would mean more pressure has to be applied on a smaller surface area.

In addition the remaining tether has to be turned aswell meaning there is more friction to overcome.

But these all increase the cost hence I'm in full agreement with @Rodders53 that you can't beat Corporation pop:

For water Mk1 kitchen tap is best  especially on a money saving site.

But then you'll need a filter round my way, unless you like the smell of chlorine..

Yes, as a child, I remember that the tap water in Birmingham was pleasant to drink. When I visited my grandmother in Kidderminster, the water tasted nasty. When I visited my other grandmother in Nice, I was forbidden from drinking tap water.

Now I live in Meriden, where the smell and taste of chlorine in the water is unpleasant. It is all about geography. Filter jugs help to an extent.

That is a good explanation.

I would suggest this is another solve a problem we do not have. A pointless "improvement" making it difficult to open for many. Anyone who is considerate enough to recycle plastic bottles would replace the cap.

Except that at one point, we were definitely supposed to put the lids in the recycling NOT attached to the bottle!

Coca Cola have had these lids for a while and I find them a blooming nuisance 
for whatever reason half the time I find it really difficult to get them back on

Yes, I know what you mean! We were at the cinema the other day, and screwing the lid back on my drink was tricky!

It may be that the drivers of corporations to find ecological solutions are so strong that considerations of advancing age and ailments are not taken into account. 

The tools proposed by previous posters have been incredibly successful and are liked by my son as well.

I have noticed a range of problems recently in tackling every day tasks. My son laughs at me as I awkawardly tackle stiles on country walks. Somehow, I lack the agility that I once had. Now my other major problem is blister packs.
