Anyway, the article was posted just 23 hours ago, so probably the acquisition of coins.ph was probably just recently. I think it's too early to say if some things are going to be different or not. If something would actually change, I hope that it's for the better.
I'm a little bit surprised that you don't know about it. It's true that the article was posted 23 hours ago but IIRC I read it since days ago
(not sure if my memory is correct though), found another link:
http://fintechnews.sg/28130/mobilepayments/go-jek-coins-ph-blockchain-acquire-grab/. In fact, it has been discussed on Indonesia Blockchain Network TG group since Friday last week. But yeah, I think it's way too early to tell the differences as they might still process the acquisition details.
hopefully the GoJek people won't want to increase fees or anything -- that would totally undermine the entire purpose of the company.
I think GoJek won't do that. They've shown a lot of interest of penetrating the Philippines market, which has failed many times because they don't get the acceptance from the government according to the news that I read. They're smart, starting from a small ride-hailing business with only 50 or so drivers to thousands at this moment. So I don't think they'll do poor strategies like increasing the fee or something like that. With their major competitor, Grab, has taken a few steps ahead of them, I think they'll let Coins.ph operate as usual first before introducing new things and policy.
