Virtue signalling and a half disguised way of increasing sales and consumerism
If they really cared about climate they'd find proper ways (more/cheaper public transport, state sponsored bicycle sharing, &c.). This is "green capitalism", just slap an "electric" sticker on it and continue with the good old ways
It's not the same use case and in congested places like central Paris people who need a motor have scooters.
Feedback stats on these schemes are important but rarely conducted or published in a transparent way as the government obviously has a vested interest in claiming that they work great.
I am sure some people will use the scheme but probably because they were thinking of getting an ebike anyway and a replacing their car for a new one...
It's the usual and main issue with those schemes: they are political decisions and don't always make practical or economical sense.
Kicking the poors while they're down and/or pulling the rug out from under people who are just barely doing better is not a sustainable way of decarbonizing society and it seems like every decarbonizing policy does just that. We can get away with a few such policies but when they're all like that it doesn't work.
Instead of renting an uber&co bikes (companies which use public infrastructure yet pay virtually no local tax) you'd rent state owned bikes, parked on official bike parkings. It could be part of your existing public transportation package &c.
It really doesn't take a genius to see how the current mayhem could be improved on so many levels
This is the next step when you already have that.
