Subscription? That sucks.... I bought it outright a bit back, it was pricey, maybe $15 CAD? (Can't remember)
Sorry to hear it has gone up so much... But that does seem to be the way of the app world... Pricey, subscription (even when they cannot possibly justify it) or both!
Of course it matters, climate change and global warming are not binary... It's not like if we go past x it's game over and the Earth will stop spinning, it's more like if we past x we can now expect shittier and shittier conditions and outcomes
Therefore, if we pass x by a bit, it'll be shitty but we may make it.... If we pass x by a mile and keep going, then all hope is lost
