Why insurance companies charge fund management fees from ULIP holders?

In the recent economic crisis, a huge number of Unit Linked Insurance policy holders suffered heavy losses. Insurance companies deduct 2.25% on a regular basis as fund management charges. Had “fund managers” switch the money from equity to debt fund on time, ULIP holders would not have suffered such heavy losses. Is there any justification in insurance companies charging fund management fee when they cannot do the job properly?
