Personally, I think the 15 minute time period is completely ridiculous and harmful to publishers. I think a 7-day trial period would be a little long, but a reasonable choice. Better yet would be to let the publisher of the app choose from a small list of options (15 min, 24 hrs, 7 days, 1 year, Forever).<p>BUT, I also realize that the app stores can't create separate policies for every jurisdiction on the planet -- there are too many and it is too difficult. So Google's "solution" is probably the best way to deal with a bad situation.
