I don't know when the price in France went up, it's been € 2.50 as far back as I can remember. I'm pretty sure it was still € 2.50 before the "my million" bit was launched.
One thing that really annoys me is their insistence over here on using weird, proprietary barcodes (with evenly-spaced, uniform-width lines of different lengths) on the tickets that only the scanners in the shops can decipher. It looks like the UK Euromillions tickets have standard QR codes on them that can be read by any barcode-scanning app.Its funny you say France isn't on the bleeding edge; they're quite innovative in some areas, although online is a bit behind the curve (App especially) imho, and they're a bit slow to change. Having said that, I don't think I could point at any lottery's online presence and say "yeah that's brilliant". We're getting there but I still don't like our clunky login (there's complicated history behind it and most lotteries have similar issues), and our website will get a lot better in a few weeks.
