As the user who doesn't like higher wagering, as long the casino not make those bonuses automatically active is fine. It always depends and the choice of the user, any promotions are really welcome as long as these typical offer is needed manually active and only by user it self (not automatically). Regarding marketing and competitor, casino want to compete each other but keep in mind not every casino having a same budget.... So you can't blame them either. They could be having some though to do some marketing, same as other competitor but cannot make it due the budget.
I am not blaming any casinos for not organizing the giveaways or bonuses that their competitors may offer. Casinos can have different marketing strategies depending on their budget. As you can see, there are hundreds of casinos on this forum. Do they all launch signature campaigns? No, but we cannot blame them for that. We cannot expect everyone to follow the same marketing strategy.
Some casinos lure users to their platforms with their deposit bonus, but once the user makes a deposit, they get stuck with their money. I guess the users are to blame here. Because they do not read the bonus terms carefully.
