The total number of active users in the last month would be a much more accurate statistic. The number of users does not give the correct result due to bot accounts.
I imagine there will still be a higher than normal amount of growth, but not as steep, through the rest of the summer as other people give up on Reddit after the changes. Some casual users may not understand what's going on, but they'll notice the changes through July and August without all the 3rd party people and the mods who leave/have left/got removed, which may drive them to alternatives.
